NAME

       filepath - return the whole search path of a file

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

SYNOPSYS

       #include "mut.h"
       char *filepath(name, extension)
       char *name, *extension;

PARAMETERS

       name		   Name of the file to be search for

       extension	   File extension

DESCRIPTION

       filepath return the absolute path of a cell.  This is useful for error messages, since the caller of mbk file  functions  is  not  able	to
       specify	explicitly  which  file  it opened.  Having such an information is also necessary when last modification times or access times are
       needed, as for consistency checks.  The file is searched through the environment  variable  MBK_WORK_LIB(1),  and  if  not  found,  through
       MBK_CATA_LIB(1) in the user defined order.
       The file to be searched is called name.extension, if extension is not NULL, else it is name. If extension is the empty string, "", then the
       file name will be name. .

RETURN VALUE

       filepath returns NULL on failure, ie the file is not in the pathes, or the absolute path on success.  The value returned, when not NULL, is
       stored in a static buffer, so this values is to use at return time or copied into a user buffer.

EXAMPLE

       #include <stdio.h>
       #include "mut.h"
       #include "mph.h"
       void vti_error(fig, error)
       phfig_list *fig;
       char *(*error)();
       {
	     fprintf(stderr, "Syntax error in %s
", filepath(fig->NAME, "cp"));
	     fprintf(stderr, "%s
", error());
       }
