OSMalloc_Tagalloc

Creates a tag for use with OSMalloc functions.

Declaration

OSMallocTag OSMalloc_Tagalloc(const char *name, uint32_t flags);

Parameters

  • name:

    The name of the tag to create.

  • flags:

    A bitmask that controls allocation behavior; see description.

Return Value

An opaque tag to be used with OSMalloc functions for tracking memory usage.

Discussion

OSMalloc tags can have arbitrary names of a length up to 63 characters. Calling this function twice with the same name creates two tags, which share that name.

flags can be the bitwise OR of the following flags:

  • OSMT_DEFAULT - allocations are wired. This is the 'zero' bitmask value and is overridden by any other flag specified.

  • OSMT_PAGEABLE - allocations of a full page size or greater are pageable; allocations smaller than a page are wired.
