/***

*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.
