NAME

       Tcl_TranslateFileName  -  convert  file  name  to  native form and replace tilde with home
       directory

SYNOPSIS

       #include <tcl.h>

       char *
       Tcl_TranslateFileName(interp, name, bufferPtr)

ARGUMENTS

       Tcl_Interp    *interp      (in)      Interpreter in which to report an error, if any.

       CONST char    *name        (in)      File name, which may start with a ``~''.

       Tcl_DString   *bufferPtr   (in/out)  If needed, this dynamic string is used to  store  the
                                            new  file name.  At the time of the call it should be
                                            uninitialized or free.  The  caller  must  eventually
                                            call Tcl_DStringFree to free up anything stored here.

DESCRIPTION

       This  utility procedure translates a file name to a form suitable for passing to the local
       operating system.  It converts network names into native form and does tilde substitution.

       If Tcl_TranslateFileName has to do tilde substitution or translate the name then  it  uses
       the   dynamic   string  at  *bufferPtr  to  hold  the  new  string  it  generates.   After
       Tcl_TranslateFileName returns  a  non-NULL  result,  the  caller  must  eventually  invoke
       Tcl_DStringFree  to  free  any information placed in *bufferPtr.  The caller need not know
       whether or not Tcl_TranslateFileName  actually  used  the  string;   Tcl_TranslateFileName
       initializes  *bufferPtr  even if it doesn't use it, so the call to Tcl_DStringFree will be
       safe in either case.

       If an error occurs (e.g. because there was no  user  by  the  given  name)  then  NULL  is
       returned  and  an  error  message will be left in the interpreter's result.  When an error
       occurs, Tcl_TranslateFileName frees the dynamic string itself so that the caller need  not
       call Tcl_DStringFree.

       The  caller  is  responsible for making sure that the interpreter's result has its default
       empty value when Tcl_TranslateFileName is invoked.
