OSErr UnlockMemory( address, count );

void * address is the start address of the memory range

unsigned long count is the size of the range

The UnlockMemory function makes a portion of the address space movable

in real memory and eligible for paging again. It undoes the effects of both

address is the start address of the range that is to be unlocked

count is the size in bytes of that range.

Returns: an operating system Error Code.

noErr (0) No error

paramErr (-50) Error in parameter list

notLockedErr (-623) Specified range of memory is not locked

interruptsMaskedErr (-624) Called with interrupts masked

Notes: If the specified address is not on a page boundary, it is rounded down to the

nearest page boundary. Similarly, if the specified range does not end on a

page boundary, the length parameter is rounded up so that the entire range

of memory is unlocked..
