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 occu- pies a static area, the pattern buffer, which is overwritten by subsequent use of re_comp. If regex is NULL, no opera- tion 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 oth- erwise it returns a pointer to an appropriate error message. re_exec returns 1 for a successful match, zero for failure.
