AvailMem -- memory available given certain requirements
size = AvailMem(attributes)
D0 D1
ULONG AvailMem(ULONG);
This function returns the amount of free memory given certain
attributes.
To find out what the largest block of a particular type is, add
MEMF_LARGEST into the requirements argument. Returning the largest
block is a slow operation.
Due to the effect of multitasking, the value returned may not
actually be the amount of free memory available at that instant.
requirements - a requirements mask as specified in AllocMem. Any
of the AllocMem bits are valid, as is MEMF_LARGEST
which returns the size of the largest block matching
the requirements.
size - total free space remaining (or the largest free block).
For V36 Exec, AvailMem(MEMF_LARGEST) does a consistency check on
the memory list. Alert AN_MemoryInsane will be pulled if any mismatch
is noted.
AvailMem(MEMF_CHIP|MEMF_LARGEST);
/* return size of largest available chip memory chunk */
