NAME    [Toc]    [Back]

       re_comp, re_exec - BSD regex functions

SYNOPSIS    [Toc]    [Back]

       #include <regex.h>

       char *re_comp(char *regex);
       int re_exec(char *string);

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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.
