          | TC: int abswrite( int drive, int sectors, int start, void *buffer )
 
 
 - prototype in dos.h
 
 - writes absolute logical disk sectors
 - drive =  (0=A:, 1=B:, 2=C:, ...)
 - sectors = # of sectors to write
 - start = beginning logical sector number
 - buffer = address of buffer
 - TC++ accounts for DOS 4.x+ long sector values while TC 2.0 and
 earlier do not (see INT 25)
 - returns 0 if OK; -1 on error; errno has DOS error number
