NewPtrSysClear
You can use theNewPtrSysClear
function to allocate, in the system heap, prezeroed memory in a nonrelocatable block of a specified size.
FUNCTION NewPtrSysClear (logicalSize: Size): Ptr;
logicalSize
- The requested size (in bytes) of the nonrelocatable block.
DESCRIPTION
TheNewPtrSysClear
function works much as theNewPtr
function does, but attempts to allocate the requested block in the system heap zone instead of in the current heap zone. Also, it sets all bytes in the new block to 0 instead of leaving the contents of the block undefined.RESULT CODES
noErr 0 No error memFullErr -108 Not enough memory
