Function Documentation
| UNIV_INTERN void mem_analyze_corruption | ( | void * | ptr | ) |
Tries to find neigboring memory allocation blocks and dumps to stderr the neighborhood of a given pointer. in: pointer to place of possible corruption
| UNIV_INTERN ibool mem_heap_check | ( | mem_heap_t * | heap | ) |
Checks that an object is a memory heap (or a block of it)
- Returns
- TRUE if ok in: memory heap
| UNIV_INTERN ibool mem_heap_validate | ( | mem_heap_t * | heap | ) |
Validates the contents of a memory heap.
- Returns
- TRUE if ok in: memory heap
| UNIV_INTERN void mem_heap_validate_or_print | ( | mem_heap_t * | heap, |
| byte * | top, | ||
| ibool | print, | ||
| ibool * | error, | ||
| ulint * | us_size, | ||
| ulint * | ph_size, | ||
| ulint * | n_blocks | ||
| ) |
Checks a memory heap for consistency and prints the contents if requested. Outputs the sum of sizes of buffers given to the user (only in the debug version), the physical size of the heap and the number of blocks in the heap. In case of error returns 0 as sizes and number of blocks. out: number of blocks in the heap, if a NULL pointer is passed as this argument, it is ignored
- Parameters
-
heap in: memory heap top in: calculate and validate only until this top pointer in the heap is reached, if this pointer is NULL, ignored print in: if TRUE, prints the contents of the heap; works only in the debug version error out: TRUE if error us_size out: allocated memory (for the user) in the heap, if a NULL pointer is passed as this argument, it is ignored; in the non-debug version this is always -1 ph_size out: physical size of the heap, if a NULL pointer is passed as this argument, it is ignored
| UNIV_INTERN void mem_print_info | ( | void | ) |
Prints information of dynamic memory usage and currently allocated memory heaps or buffers. Can only be used in the debug version.
| UNIV_INTERN void mem_print_new_info | ( | void | ) |
Prints information of dynamic memory usage and currently allocated memory heaps or buffers since the last ..._print_info or..._print_new_info.
