Functions | |
| void | rtxMemSetAllocFuncs (OSMallocFunc malloc_func, OSReallocFunc realloc_func, OSFreeFunc free_func) |
| This function sets the pointers to standard allocation functions. | |
| void | rtxMemSetDefBlkSize (OSUINT32 blkSize) |
| This function sets the minimum size and the granularity of memory blocks for newly created memory heaps. | |
| OSUINT32 | rtxMemGetDefBlkSize () |
| This function returns the actual granularity of memory blocks. | |
| OSBOOL | rtxMemIsZero (const void *pmem, size_t memsiz) |
| This helper function determines if an arbitrarily sized block of memory is set to zero. | |
