re_comp(3)

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
       occupies a static area, the pattern buffer, which is over-
       written 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 com-
       piled 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  fail-
       ure.
