__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_GetCwd, Tcl_Chdir - manipulate the current working directory

SYNOPSIS

       #include <tcl.h>

       char *
       Tcl_GetCwd(interp, bufferPtr)

       int
       Tcl_Chdir(path)

ARGUMENTS

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

       Tcl_DString *bufferPtr (in/out)	    This dynamic string is used to store the current working directory.  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.

       char *path (in)			    File path in UTF-8 format.
_________________________________________________________________

DESCRIPTION

       These  procedures  may  be  used  to manipulate the current working directory for the application.  They provide C-level access to the same
       functionality as the Tcl pwd command.

       Tcl_GetCwd returns a pointer to a string specifying the current directory, or NULL if the current directory could not  be  determined.	If
       NULL  is  returned,  an	error message is left in the interp's result.  Storage for the result string is allocated in bufferPtr; the caller
       must call Tcl_DStringFree() when the result is no longer needed.  The format of the path is UTF-8.

       Tcl_Chdir changes the applications current working directory to the value specified in path.  The format of the passed in  string  must	be
       UTF-8.  The function returns -1 on error or 0 on success.
