TC: int _read( int handle, void *buf, int size )
- prototype in io.h
- reads "size" bytes from file "handle" into "buf"
- size must be less than 65534 bytes
- is a direct call to MS-DOS read function INT 21,3F

- returns number of bytes successfully transferred or -1
- MS C uses _dos_read()
- see read() _open() _creat() _write() _close()
