Tcl_GetCwd(3) Tcl Library Procedures Tcl_GetCwd(3)
NAME
Tcl_GetCwd, Tcl_Chdir - manipulate the current working directory
SYNOPSIS
#include <tcl.h>
char *
Tcl_GetCwd(interp, bufferPtr)
int
Tcl_Chdir(path)
ARGUMENTS
Interpreter in which to report an error, if any. 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. File path in
UTF-8 format.
DESCRIPTION
These procedures may be used to manipulate the current working direc-
tory 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 direc-
tory, 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.
