Repost: source for string routines wanted

[G.Narotham Reddy]

I would like to know if there is any public domain source for the
following AT&T Unix Rel 4.0/(386) functions.

I would like to have these on a 3b2.
=====================================


1. srchtxt(1) - display contents of, or serch for a text string in, message
   data bases

2. addseverity(3C) - builds a list of severity levels for an application
   for use with fmtmsg
	Synopsis:  int addseverity( int severity, const char *string);

3. gettxt(3C) - retrieve a text string
	Synopsis: chat *gettxt( const *msgid, const char *dflt_str);

4. fmtmsg(3C) - display a message on stderr or system console

	int fmtmsg( long classification, const char *label, int severity,
		    const char *text, const char *action, const char *tag)

5. setlocale(3C) - modify and query a program's locale

	Synopsis:   char *setlocale( int category, const char * locale)

	* The above ones are Rel 4.0(386) Unix functions and would like to
	  get a public domain source or equivalents if there are any.

 An early response would be grately appreciated.
