`set_curdir`

#include "sfldir.h"
int
set_curdir (
    const char *path)

Synopsis

Sets the current working directory as specified. Returns 0 if the directory path was found; -1 if there was an error. Under Windows, replaces '/' by '\' before changing directory, and switches to the specified disk if the path starts with a letter and ':'. Does nothing if the path is NULL or empty.
