_dir_remove()
Remove a directory

Call

#include <vv_dir.h>

int _dir_remove(pathp)
UCHAR *pathp;	    Name of directory to delete

Returns

1	 Success.  Directory removed.

0	 Failure.  Directory not removed.

Description

Removes a directory from the file system.  This function exists in order to
provide a common interface for removing directories under different OS's.

PCDOS, UNIX and POSIX:
Uses rmdir() but change the return value to Vermont Views standard.

Note:  For those UNIX systems where rmdir() is not in the C library this
routine will perform a system call.  If your system is one of these please
#define NO_DIR_FUNC 1 in vv_env.h to enable this functionality.

VMS:
Use RMS calls to first change the file protection bits on the directory file
and then delete the file.

Cautions

The directory must be empty and must not be the current directory.
