These +functions allow access to the filesystem to check if a certain +file exists, to get its size, etc. + +In addition to these functions, a string constant DIR-SEPARATOR +has been defined. It should be used in scripts which build file +names that include one or more directories to keep the scripts +portable to different operating systems. + +(file-exists? filename) + filename: string + + This function returns #t if the indicated file exists, and + #f if it does not exist or if it is not accessible to the + requesting user. Accessibility is based on the real user + and group ID rather than the effective user ID and group ID. + +(file-type filename) + filename: string + + This function returns a value based on the file type. It + returns FILE_TYPE_FILE (1) for regular files, FILE_TYPE_DIR + (2) for directories, and FILE_TYPE_LINK (3) for symbolic + links. The value FILE_TYPE_OTHER (0) is returned if the file + is of some other type, does not exist, or if the user does + not have sufficient privileges to allow the file type to be + determined. + +(file-size filename) + filename: string + + This function returns the size (in bytes) of the + indicated file, or #f if the file does not exists or + is not accessible to the requesting user. + +(file-delete filename) + filename: string + + Removes the specified file. It returns #t if the operation + succeeds, or #f otherwise (e.g., because the file is + read-only, or because the file does not exist). + +(dir-open-stream path) + path: string + + Opens a "directory stream" on the provided directory path. + This stream will provide all the files within the directory, + using the function read-dir-entry. The stream should be closed + at the end with dir-close-stream. + +(dir-read-entry dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + It returns the name of the following directory entry, or eof + if all the entries were provided. Check the return value with + with eof-object?. + +(dir-rewind dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + Resets the given directory stream. The next call to dir-read-entry + will return the first entry again. It returns #t if the operation + succeeds, or #f otherwise (ie. dirstream not valid).. + +(dir-close-stream dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + Close directory stream. No further calls to read-dir-entry should + be performed. + + +*Time (available if HAVE_TIME is defined in tsx.h) + +(time) + Returns the current local time, as a list of integer + containing: + (year month day-of-month hour min sec millisec) + The year is expressed as an offset from 1900. + +(gettimeofday) + Returns a list containing the number of seconds from + the beginning of the day, and microseconds within the + current second. + +(usleep microsec) + microsec: integer + + Suspends execution of the calling thread during the + specified number of microseconds. + + +END + -- cgit v1.2.3
