NAME
- TypeOfMem
-
determine attributes of a given memory address
SYNOPSIS
attributes = TypeOfMem(address)
D0 A1
ULONG TypeOfMem(void *);
D0 A1
ULONG TypeOfMem(void *);
FUNCTION
Given a RAM memory address, search the system memory lists and return its memory attributes. The memory attributes are similar to those specified when the memory was first allocated: (eg. MEMF_CHIP and MEMF_FAST).
This function is usually used to determine if a particular block of memory is within CHIP space.
If the address is not in known-space, a zero will be returned. (Anything that is not RAM, like the ROM or expansion area, will return zero. Also the first few bytes of a memory area are used up by the MemHeader.)

INPUT
- address
-
a memory address
RESULT
- attributes
-
a long word of memory attribute flags.
WARNING
Memory allocation and deallocation as well as querying how much memory is available requires a Task or, by extension, a Process. None of the exec kernel memory management operations is safe to call from interrupt code!
