Mac OS For QuickTime Programmers

Memory Management

Two chapters describe routines in Mac OS that help you create and dispose of pointers and handles. "Introduction to Memory Management," describes memory management within an application's memory partition; "Memory Manager," describes memory management outside the partition. The following functions are described in both chapters:

NewHandle allocates a relocatable memory block of a specified size within an application's memory partition. To use it outside an application's memory partition, see [link] .
NewHandleClear allocates prezeroed memory in a relocatable block of a specified size within an application's memory partition. To use it outside an application's memory partition, see [link] .
DisposeHandle frees a relocatable block and its master pointer for other uses within an application's memory partition. To use it outside an application's memory partition, see [link] .
NewPtr allocates a nonrelocatable block of memory of a specified size within an application's memory partition. To use it outside an application's memory partition, see [link] .
NewPtrClear allocates prezeroed memory in a nonrelocatable block of a specified size within an application's memory partition. To use it outside an application's memory partition, see [link] .
DisposePtr frees a nonrelocatable block for other uses within an application's memory partition. To use it outside an application's memory partition, see [link] .
