The data files +to be loaded are specified in the `masks' parameter as a bitwise combination +of the macros listed above. +.sp +This should be called before using any of the other functions. +.TP 4 +.BR ucdata_unload() +This function unloads the data tables specified in the `masks' parameter. +.sp +This function should be called when the application is done using the UCData +package. +.TP 4 +.BR ucdata_reload() +This function reloads the data files from one of the colon-separated +directories in the `paths' parameter. The data files to be reloaded are +specified in the `masks' parameter as a bitwise combination of the macros +listed above. +.TP 4 +.BR ucdecomp() +This function determines if a character has a decomposition and returns the +decomposition information if it exists. +.sp +If a zero is returned, there is no decomposition. If a non-zero is +returned, then the `num' and `decomp' variables are filled in with the +appropriate values. +.sp +Example call: +.sp +.nf + unsigned long i, num, *decomp; + + if (ucdecomp(0x1d5, &num, &decomp) != 0) { + for (i = 0; i < num; i++) + printf("0x%08lX,", decomp[i]); + putchar('\n'); + } +.TP 4 +.BR uccanondecomp() +This function will decompose a string, insuring the characters are in +canonical order for comparison. +.sp +If a decomposed string is returned, the caller is responsible for deallocating +the string. +.sp +If a -1 is returned, memory allocation failed. If a zero is returned, no +decomposition was done. Any other value means a decomposition string was +created and the values returned in the `out' and `outlen' parameters. +.TP 4 +.BR ucdecomp_hangul() +This function determines if a Hangul syllable has a +decomposition and returns the decomposition information. +.sp +An array of at least size 3 should be passed to the function +for the decomposition of the syllable. +.sp +If a zero is returned, the character is not a Hangul +syllable. If a non-zero is returned, the `num' field +will be 2 or 3 and the syllable will be decomposed into +the `decomp' array arithmetically. +.sp +Example call: +.sp +.nf + unsigned long i, num, decomp[3]; + + if (ucdecomp_hangul(0xb1ba, &num, &decomp) != 0) { + for (i = 0; i < num; i++) + printf("0x%08lX,", decomp[i]); + putchar('\n'); + } +.TP 4 +.BR uccomp() +This function determines if a pair of characters have a composition, and +returns that composition if one exists. +.sp +A zero is returned is no composition exists for the character pair. Any other +value indicates the `comp' field holds the character code representing the +composition of the two character codes. +.TP 4 +.BR uccomp_hangul() +This composes the Hangul Jamo in-place in the string. +.sp +The returned value is the new length of the string. +.TP 4 +.BR uccanoncomp() +This function does a full composition in-place in the string, including the +Hangul composition. +.sp +The returned value is the new length of the string. +.TP 4 +.BR ucnumber_lookup() +This function determines if the code is a number and +fills in the `num' field with the numerator and +denominator. If the code happens to be a single digit, +the numerator and denominator fields will be the same. +.sp +If the function returns 0, the code is not a number. +Any other return value means the code is a number. +.TP 4 +.BR ucdigit_lookup() +This function determines if the code is a digit and +fills in the `digit' field with the digit value. +.sp +If the function returns 0, the code is not a number. +Any other return value means the code is a number. +.TP 4 +.BR ucgetnumber() +This is a compatibility function with John Cowan's +"uctype" package. It uses ucnumber_lookup(). +.TP 4 +.BR ucgetdigit() +This is a compatibility function with John Cowan's +"uctype" package. It uses ucdigit_lookup(). +.TP 4 +.BR uctoupper() +This function returns the code unchanged if it is +already upper case or has no upper case equivalent. +Otherwise the upper case equivalent is returned. +.TP 4 +.BR uctolower() +This function returns the code unchanged if it is +already lower case or has no lower case equivalent. +Otherwise the lower case equivalent is returned. +.TP 4 +.BR uctotitle() +This function returns the code unchanged if it is +already title case or has no title case equivalent. +Otherwise the title case equivalent is returned. +.TP 4 +.BR ucisalpha() +Test if \fIcode\fR is an alpha character. +.TP 4 +.BR ucisalnum() +Test if \fIcode\fR is an alpha or digit character. +.TP 4 +.BR ucisdigit() +Test if \fIcode\fR is a digit character. +.TP 4 +.BR uciscntrl() +Test if \fIcode\fR is a control character. +.TP 4 +.BR ucisspace() +Test if \fIcode\fR is a space character. +.TP 4 +.BR ucisblank() +Test if \fIcode\fR is a blank character. +.TP 4 +.BR ucispunct() +Test if \fIcode\fR is a punctuation character. +.TP 4 +.BR ucisgraph() +Test if \fIcode\fR is a graphical (visible) character. +.TP 4 +.BR ucisprint() +Test if \fIcode\fR is a printable character. +.TP 4 +.BR ucisxdigit() +Test if \fIcode\fR is a hexadecimal digit character. +.TP 4 +.BR ucisupper() +Test if \fIcode\fR is an upper case character. +.TP 4 +.BR ucislower() +Test if \fIcode\fR is a lower case character. +.TP 4 +.BR ucistitle() +Test if \fIcode\fR is a title case character. +.TP 4 +.BR ucisisocntrl() +Is the character a C0 control character (< 32)? +.TP 4 +.BR ucisfmtcntrl() +Is the character a format control character? +.TP 4 +.BR ucissymbol() +Is the character a symbol? +.TP 4 +.BR ucisnumber() +Is the character a number or digit? +.TP 4 +.BR ucisnonspacing() +Is the character non-spacing? +.TP 4 +.BR ucisopenpunct() +Is the character an open/left punctuation (i.e. '[') +.TP 4 +.BR ucisclosepunct() +Is the character an close/right punctuation (i.e. ']') +.TP 4 +.BR ucisinitialpunct() +Is the character an initial punctuation (i.e. U+2018 LEFT +SINGLE QUOTATION MARK) +.TP 4 +.BR ucisfinalpunct() +Is the character a final punctuation (i.e. U+2019 RIGHT +SINGLE QUOTATION MARK) +.TP 4 +.BR uciscomposite() +Can the character be decomposed into a set of other +characters? +.TP 4 +.BR ucisquote() +Is the character one of the many quotation marks? +.TP 4 +.BR ucissymmetric() +Is the character one that has an opposite form +(i.e. <>) +.TP 4 +.BR ucismirroring() +Is the character mirroring (superset of symmetric)? +.TP 4 +.BR ucisnonbreaking() +Is the character non-breaking (i.e. non-breaking +space)? +.TP 4 +.BR ucisrtl() +Does the character have strong right-to-left +directionality (i.e. Arabic letters)? +.TP 4 +.BR ucisltr() +Does the character have strong left-to-right +directionality (i.e. Latin letters)? +.TP 4 +.BR ucisstrong() +Does the character have strong directionality? +.TP 4 +.BR ucisweak() +Does the character have weak directionality +(i.e. numbers)? +.TP 4 +.BR ucisneutral() +Does the character have neutral directionality +(i.e. whitespace)? +.TP 4 +.BR ucisseparator() +Is the character a block or segment separator? +.TP 4 +.BR ucislsep() +Is the character a line separator? +.TP 4 +.BR ucispsep() +Is the character a paragraph separator? +.TP 4 +.BR ucismark() +Is the character a mark of some kind? +.TP 4 +.BR ucisnsmark() +Is the character a non-spacing mark? +.TP 4 +.BR ucisspmark() +Is the character a spacing mark? +.TP 4 +.BR ucismodif() +Is the character a modifier letter? +.TP 4 +.BR ucismodifsymbol() +Is the character a modifier symbol? +.TP 4 +.BR ucisletnum() +Is the character a number represented by a letter? +.TP 4 +.BR ucisconnect() +Is the character connecting punctuation? +.TP 4 +.BR ucisdash() +Is the character dash punctuation? +.TP 4 +.BR ucismath() +Is the character a math character? +.TP 4 +.BR uciscurrency() +Is the character a currency character? +.TP 4 +.BR ucisenclosing() +Is the character enclosing (i.e. enclosing box)? +.TP 4 +.BR ucisprivate() +Is the character from the Private Use Area? +.TP 4 +.BR ucissurrogate() +Is the character one of the surrogate codes? +.TP 4 +.BR ucisidentstart() +Is the character a legal initial character of an identifier? +.TP 4 +.BR ucisidentpart() +Is the character a legal identifier character? +.TP 4 +.BR ucisdefined() +Is the character defined (appeared in one of the data +files)? +.TP 4 +.BR ucisundefined() +Is the character not defined (non-Unicode)? +.TP 4 +.BR ucishan() +Is the character a Han ideograph? +.TP 4 +.BR ucishangul() +Is the character a pre-composed Hangul syllable? + +.SH "SEE ALSO" +ctype(3) + +.SH ACKNOWLEDGMENTS +These are people who have helped with patches or +alerted me about problems. +.sp +John Cowan <cowan@locke.ccil.org> +.br +Bob Verbrugge <bob_verbrugge@nl.compuware.com> +.br +Christophe Pierret <cpierret@businessobjects.com> +.br +Kent Johnson <kent@pondview.mv.com> +.br +Valeriy E.
