- NAME
- f1gpAllocQuitNotify -- ask to be notified when F1GP quits.
-
- SYNOPSIS
- handle = f1gpAllocQuitNotify( task, signal )
- D0 A0 D0
-
- APTR f1gpAllocQuitNotify( struct Task *, ULONG );
-
- FUNCTION
- This function allows a task to be notified when F1GP quits. When
- F1GP quits the 2 parameters are passed directly to Exec Signal(),
- allowing the calling task to pick up the singal on its port using
- Exec Wait(). This can be used to allow programs to quit as soon
- as F1GP quits, remove patches, etc.
-
- A single task should only call this function once, usually during
- initialization. It DOES NOT require that F1GP is in memory.
-
- This call MUST be matched with a call to f1gpFreeQuitNotify(),
- typically just before the calling task exits.
-
- INPUTS
- task - pointer to a task, which is usually the calling task
- (ie FindTask(NULL)).
- signal - signal to be sent to the task.
-
- RESULTS
- handle - a pointer to an internal structure if successful,
- otherwise NULL.

-
- NAME
- f1gpCalcChecksum -- Compute a standard F1GP file checksum. (V35)
-
- SYNOPSIS
- checksum = f1gpCalcChecksum( data, datasize )
- D0 A0 D0
-
- ULONG f1gpCalcChecksum( UBYTE *, ULONG );
-
- FUNCTION
- If you intend to alter any of F1GP's files (eg track files), you
- will need to rewrite the 4 byte checksum also (last 4 bytes of file).
- This function calculates the correct checksum from the given input
- data and returns it as a ULONG.
-
- INPUTS
- data - a pointer to the array of bytes which you intend to save.
- datasize - the size of the data array (in bytes), NOT including the
- checksum space (4 bytes).
-
- RESULTS
- checksum - the 4 byte checksum that is usually located at the end
- of F1GP's files (ie the last 4 bytes).
-
- f1gp.library/f1gpDetect f1gp.library/f1gpDetect
-
- NAME
- f1gpDetect -- Inquire whether F1GP is running in memory.
-
- SYNOPSIS
- type = f1gpDetect();
- D0
-
- LONG f1gpDetect( void );
-
- FUNCTION
- This function scans the Exec task lists to determine whether F1GP
- is currently running in memory. If F1GP is resident then the type
- is returned and HunkStart, Seg1, Seg3 in the F1GPBase structure
- will be updated. The type is also stored in the F1GPType field
- in the F1GPBase structure.
-
- Each time this function is called the priority of F1GP is set to
- -100, to stop it hogging processor time.
-
- RESULTS
- type - if F1GP was detected in memory, this will be indicate
- what version of F1GP it is. This will be one of
- F1GPTYPE_STANDARD, F1GPTYPE_WC or F1GPTYPE_A600WWW.
- If not detected, the value will be 0.

- f1gp.library/f1gpFreeQuitNotify f1gp.library/f1gpFreeQuitNotify
-
- NAME
- f1gpFreeQuitNotify -- Free memory after f1gpAllocQuitNotify().
-
- SYNOPSIS
- f1gpFreeQuitNotify( handle )
- A0
-
- void f1gpFreeQuitNotify( APTR );
-
- FUNCTION
- Frees memory allocated by a call to f1gpAllocQuitNotify(), which
- also means the calling task will no longer be notified when F1GP
- quits. The pointer passed in MUST have been obtained by
- f1gpAllocQuitNotify().
-
- If NULL is passed in this function does nothing.
-
- INPUTS
- handle - pointer returned from f1gpAllocQuitNotify() or NULL.
