/***
*int _creat(path, pmode) - create a new file
*
*Purpose:
*	If file specified does not exist, _creat creates a new file
*	with the given permission setting and opens it for writing.
*	If the file already exists and its permission allows writing,
*	_creat truncates it to 0 length and open it for writing.
*	The only Xenix mode bit supprted by DOS is user write (S_IWRITE).
*
*Entry:
*	_TSCHAR *path - filename to create
*	int pmode - permission mode setting for new file
*
*Exit:
*	returns handle for created file
*	returns -1 and sets errno if fails.
*
*Exceptions:
