18 re_comp() is used to compile the null-terminated regular expression
19 pointed to by regex. The compiled pattern occupies a static area, the
20 pattern buffer, which is overwritten by subsequent use of re_comp().
21 If regex is NULL, no operation is performed and the pattern buffer's
22 contents are not altered.
23
24 re_exec() is used to assess whether the null-terminated string pointed
25 to by string matches the previously compiled regex.
26
28 re_comp() returns NULL on successful compilation of regex otherwise it
29 returns a pointer to an appropriate error message.
30
31 re_exec() returns 1 for a successful match, zero for failure.

37 These functions are obsolete; the functions documented in regcomp(3)
38 should be used instead.
