re_comp(3)                            GNU                           re_comp(3)



NAME
       re_comp, re_exec - BSD regex functions

SYNOPSIS
       #include <sys/types.h>
       #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  con-
       tents 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.
