_chdrive
Visual Studio 2008
Changes the current working drive.
int _chdrive( int drive );
The _chdrive function changes the current working drive to the drive specified by drive. The drive parameter uses an integer to specify the new working drive (1=A, 2=B, and so forth). This function changes only the working drive; _chdir changes the working directory.
If drive does not specify a valid drive, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, the function returns -1 and errno is set to EACCES, and _doserrno is set to ERROR_INVALID_DRIVE.
