Tcl_GetCwd, Tcl_Chdir - manipulate the current working directory
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_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.
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.
