11.13 Semaphores in MagiC

Under MagiC, semaphores are released when the program (more exactly the application) terminates. In contrast to MiNT this applies also to the semaphores allocated with Psemaphore.

MagiCsupports with Psemaphore only modes 2 and 3 at present, and recognizes the following system semaphores:

Semaphore Meaning
   
_DMA ACSI and FDC
On receipt of these semaphores one must not forget to set the system variable flock, and also to release this again after the semaphore is released
_NCR SCSI of the Atari-TT
_SCR AES screen (used by wind_update)
