+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBBN_ULONG\fR is a macro that will be an unsigned integral type optimized
+for the most efficient implementation on the local platform.
+.PP
+\&\fBBN_zero()\fR, \fBBN_one()\fR and \fBBN_set_word()\fR set \fBa\fR to the values 0, 1 and
+\&\fBw\fR respectively.  \fBBN_zero()\fR and \fBBN_one()\fR are macros.
+.PP
+\&\fBBN_value_one()\fR returns a \fBBIGNUM\fR constant of value 1. This constant
+is useful for use in comparisons and assignment.
+.PP
+\&\fBBN_get_word()\fR returns \fBa\fR, if it can be represented as a \fBBN_ULONG\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBBN_get_word()\fR returns the value \fBa\fR, or all-bits-set if \fBa\fR cannot
+be represented as a single integer.
+.PP
+\&\fBBN_one()\fR and \fBBN_set_word()\fR return 1 on success, 0 otherwise.
+\&\fBBN_value_one()\fR returns the constant.
+\&\fBBN_zero()\fR never fails and returns no value.
+.SH BUGS
+.IX Header "BUGS"
+If a \fBBIGNUM\fR is equal to the value of all-bits-set, it will collide
+with the error condition returned by \fBBN_get_word()\fR which uses that
+as an error value.
+.PP
+\&\fBBN_ULONG\fR should probably be a typedef.

+.SH HISTORY
+.IX Header "HISTORY"
+In OpenSSL 0.9.8, \fBBN_zero()\fR was changed to not return a value; previous
+versions returned an int.
