re_comp (ULTRIX)					      re_comp (ULTRIX)

NAME
       re_comp, re_exec - Handle regular expressions

LIBRARY
       Standard C Library (libc.a)

BSD COMPATIBILITY
       The  Digital  UNIX system provides the libbsd.a library to allow you to
       use library functions that are compatible with ULTRIX BSD library func‐
       tions. To use the BSD functions, your program needs to be compiled with
       -D_BSD and the -lbsd options.

       Converts a string into an internal form suitable for pattern  matching.
       Returns 0 if the string was compiled successfully; otherwise, returns a
       pointer to an error message. The	 regular  expressions  recognized  are
       described in the grep(1) reference page.

       The  re_exec()  function	 compares  the	string parameter with the last
       string passed to the  re_comp()	function.  Returns  1  if  the	string
       matches	the  last  compiled regular expression. (The default returns 1
       when the string fails to match the regular expression.)	Returns	 0  if
       the  string  fails  to match the last compiled regular expression. (The
       default returns 0 if the string does  match  the	 regular  expression.)
       Returns -1 if the compiled regular expression is invalid (indicating an
       internal error).
