RE_COMP(3) Linux Programmer's Manual RE_COMP(3)

NAME

     re_comp, re_exec - BSD regex functions

SYNOPSIS

     #define _REGEX_RE_COMP
     #include <sys/types.h>
     #include <regex.h>
     char *re_comp(const char *regex);
     int re_exec(const 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.
