 .SH NAME
 Tcl_GetCwd, Tcl_Chdir \- manipulate the current working directory
 .SH SYNOPSIS
 .nf
 \fB#include <tcl.h>\fR
 .sp
 char *
 \fBTcl_GetCwd\fR(\fIinterp\fR, \fIbufferPtr\fR)
 .sp
 int
 \fBTcl_Chdir\fR(\fIpath\fR)
 .SH ARGUMENTS
 .AS Tcl_DString *bufferPtr
 .AP Tcl_Interp *interp in
 Interpreter in which to report an error, if any.
 .AP 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 \fBTcl_DStringFree\fR to free up
 anything stored here.
 .AP char *path in
 File path in UTF\-8 format.
 .BE

 .SH DESCRIPTION
 .PP
 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 \fBpwd\fR command.
 .PP
 \fBTcl_GetCwd\fR 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 \fBTcl_DStringFree()\fR when the result is no longer needed.
 The format of the path is UTF\-8.
 .PP
 \fBTcl_Chdir\fR changes the applications current working directory to
 the value specified in \fIpath\fR.  The format of the passed in string
 must be UTF\-8.  The function returns -1 on error or 0 on success.
