Tcl_TranslateFileName()

convert file name to native form and replace tilde with homedirectory 

Tcl Library Procedures

SYNOPSIS

#include <tcl.h>

char * Tcl_TranslateFileName(interp, name, bufferPtr)

ARGUMENTS

Tcl_Interp *interp (in) 

Interpreter in which to report an error, if any.

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 (for example, 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.
