Debugger Support Under Virtual Memory

void * address is the start address of the range that is to be

locked in RAM

unsigned long count is the size in bytes of that range

returns Error Code; 0=no error

The DebuggerLockMemory function performs the same operations as

LockMemory, except that it leaves data caching enabled on the affected

pages.

address is the start address of the range that is to be locked in RAM

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

notEnoughMemoryErr (-620) Insufficient physical memory

Notes: If the starting address parameter supplied to the DebuggerLockMemory

function is not on a page boundary, then 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 locked.
