The following subroutines handle regular expressions:
|regcomp||Compiles a regular expression for comparison by the regexec subroutine.|
|regerror||Returns the error message, appropriate for the current locale, that corresponds to the error code returned by either the regcomp or regexec subroutine.|
|regexec||Compares a string with a compiled regular expression from a previous call to the regcomp subroutine.|
|regfree||Frees any memory allocated by a previous call to the regcomp subroutine.|
