re_comp Section: GNU (3) Updated: July 14th 1995 Index   NAME re_comp, re_exec - BSD regex functions   SYNOPSIS #include <regex.h> char *re_comp(char *regex); int re_exec(char *string);   DESCRIPTION re_comp is used to compile the null-terminated regular expression pointed to by regex. The compiled pattern occupies a static area, the pattern buffer, which is overwritten by subsequent use of re_comp. If regex is NULL, no operation is performed and the pattern buffer's contents are not altered. re_exec is used to assess whether the null-terminated string pointed to by string matches the previously compiled regex.   RETURN VALUE re_comp returns NULL on successful compilation of regex otherwise it returns a pointer to an appropriate error message. re_exec returns 1 for a successful match, zero for failure.   CONFORMING TO BSD 4.3   SEE ALSO GNU regex manual   Index NAME SYNOPSIS DESCRIPTION RETURN VALUE CONFORMING TO SEE ALSO This document was created by using the manual pages.
