regcmp


NAME
     regcmp - regular expression compile

SYNOPSIS
     regcmp [-] filename...

DESCRIPTION
     The regcmp command performs a  function  similar  to  regcmp
     and,  in  most  cases, precludes the need for calling regcmp
     from C programs. Bypassing regcmp saves  on  both  execution
     time and program size. The command regcmp compiles the regu-
     lar  expressions  in  filename  and  places  the  output  in
     filename.i.

OPTIONS
     -        If the - option is used, the output  is  placed  in
              filename.c.  The format of entries in filename is a
              name (C variable) followed by one  or  more  blanks
              followed   by   one  or  more  regular  expressions
              enclosed in double quotes. The output of regcmp  is
              C  source  code.  Compiled  regular expressions are
              represented  as  extern  char  vectors.  filename.i
              files  may  thus  be  #included  in  C programs, or
              filename.c files may be compiled and later  loaded.
              In  the  C  program  that  uses  the regcmp output,
              regex(abc,line)  applies  the  regular   expression
              named   abc   to   line.   Diagnostics   are  self-
              explanatory.



EXAMPLES
     Example 1: Examples of the regcmp command.


     name     "([A-Za-z][A-Za-z0-9_]*)$0"



     telno    "\({0,1}([2-9][01][1-9])$0\){0,1} *"

              "([2-9][0-9]{2})$1[ -]{0,1}"

              "([0-9]{4})$2"




     The three arguments to telno shown above must all be entered
     on one line.


     In the C program that uses the regcmp output,

          regex(telno, line, area, exch, rest)
     applies the regular expression named telno to line.

ENVIRONMENT VARIABLES
     A general description of the usage of the LC_* environmental
     variables can be found in environ(5).

     LC_CTYPE        Determines how  regcmp  handles  characters.
                     When  LC_CTYPE  is  set  to  a  valid value,
                     regcmp  can  display  and  handle  text  and
                     filenames  containing  valid  characters for
                     that locale.



     LC_MESSAGES     Determines how  diagnostic  and  informative
                     messages  are  presented.  This includes the
                     language and style of the messages, and  the
                     correct  form  of  affirmative  and negative
                     responses.  In the "C" locale, the  messages
                     are  presented  in the default form found in
                     the program  itself  (in  most  cases,  U.S.
                     English).
