This function returns a copy of the current memory map. The map is an array of

|
memory descriptors, each of which describes a contiguous block of memory.
|
|
|
|
@param MemoryMapSize A pointer to the size, in bytes, of the
|
|
MemoryMap buffer. On input, this is the size of
|
|
the buffer allocated by the caller. On output,
|
|
it is the size of the buffer returned by the
|
|
firmware if the buffer was large enough, or the
|
|
size of the buffer needed to contain the map if
|
|
the buffer was too small.
|
|
@param MemoryMap A pointer to the buffer in which firmware places
|
|
the current memory map.
|
|
@param MapKey A pointer to the location in which firmware
|
|
returns the key for the current memory map.
|
|
@param DescriptorSize A pointer to the location in which firmware
|
|
returns the size, in bytes, of an individual
|
|
EFI_MEMORY_DESCRIPTOR.
|
|
@param DescriptorVersion A pointer to the location in which firmware
|
|
returns the version number associated with the
|
|
EFI_MEMORY_DESCRIPTOR.
|

|
@retval EFI_SUCCESS The memory map was returned in the MemoryMap
|

buffer.

@retval EFI_BUFFER_TOO_SMALL The MemoryMap buffer was too small. The current
|

buffer size needed to hold the memory map is
|
|
returned in MemoryMapSize.
