RECOMP(3) Linux Programmer's Manual RECOMP(3)

NAME
       recomp, reexec - BSD regex functions

SYNOPSIS
       #define REGEXRECOMP
       #include 
       #include 

       char *recomp(char *regex);

       int reexec(char *string);

DESCRIPTION
       recomp()  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 recomp().
       If regex is NULL, no operation is performed and  the  pattern  buffer's
       contents are not altered.

       reexec()  is used to assess whether the null-terminated string pointed
       to by string matches the previously compiled regex.

RETURN VALUE
       recomp() returns NULL on successful compilation of regex otherwise  it
       returns a pointer to an appropriate error message.

       reexec() returns 1 for a successful match, zero for failure.
