◆mi_block_visit_fun

| typedef bool mi_block_visit_fun(const mi_heap_t *heap, const [mi_heap_area_t](#structmi__heap area t) *area, void *block, size_t block_size, void *arg) |

Visitor function passed to mi_heap_visit_blocks()

Returns_true_ if ok, false to stop visiting (i.e. break)

This function is always first called for every area with block as a NULL pointer. If visit_all_blocks was true, the function is then called for every allocated block in that area.

Function Documentation

◆mi_abandoned_visit_blocks()

| bool mi_abandoned_visit_blocks | ( | mi_subproc_id_t | subproc_id, | | | | int | heap_tag, | | | | bool | visit_blocks, | | | | mi_block_visit_fun * | visitor, | | | | void * | arg ) |

v1 , v2 : Visit all areas and blocks in abandoned heaps.

Parameters

| subproc_id | The sub-process id associated with the abandoned heaps. | | heap_tag | Visit only abandoned memory with the specified heap tag, use -1 to visit all abandoned memory. | | visit_blocks | If true visits all allocated blocks, otherwise visitor is only called for every heap area. | | visitor | This function is called for every area in the heap (with block as NULL). If visit_all_blocks is true, visitor is also called for every allocated block in every area (with block!=NULL). return false from this function to stop visiting early. | | arg | extra argument passed to the visitor. |

Returns_true_ if all areas and blocks were visited.

Note: requires the option mi_option_visit_abandoned() to be set at the start of the program.

◆mi_heap_visit_blocks()

| bool mi_heap_visit_blocks | ( | const mi_heap_t * | heap, | | | | bool | visit_blocks, | | | | mi_block_visit_fun * | visitor, | | | | void * | arg ) |

Visit all areas and blocks in a heap.

Parameters

| heap | The heap to visit. | | visit_blocks | If true visits all allocated blocks, otherwise visitor is only called for every heap area. | | visitor | This function is called for every area in the heap (with block as NULL). If visit_all_blocks is true, visitor is also called for every allocated block in every area (with block!=NULL). return false from this function to stop visiting early. | | arg | Extra argument passed to visitor. |

Returns_true_ if all areas and blocks were visited.

Note: requires the option mi_option_visit_abandoned() to be set at the start of the program to visit all abandoned blocks as well.
