Detailed Description

First-class heaps that can be destroyed in one go.

Typedef Documentation

◆ mi_heap_t

typedef struct mi_heap_s mi_heap_t

Type of first-class heaps.

A heap can only be used for (re)allocation in the thread that created this heap! Any allocated blocks can be freed by any other thread though.

Function Documentation

◆ mi_heap_calloc()

void* mi_heap_calloc	(	mi_heap_t *	heap,
		size_t	count,
		size_t	size
	)

Allocate count zero-initialized elements in a specific heap.

See also: mi_calloc()

◆ mi_heap_delete()

void mi_heap_delete ( mi_heap_t * heap )

Delete a previously allocated heap.

This will release resources and migrate any still allocated blocks in this heap (efficienty) to the default heap.

If heap is the default heap, the default heap is set to the backing heap.

◆ mi_heap_destroy()

void mi_heap_destroy ( mi_heap_t * heap )

Destroy a heap, freeing all its still allocated blocks.

Use with care as this will free all blocks still allocated in the heap. However, this can be a very efficient way to free all heap memory in one go.

If heap is the default heap, the default heap is set to the backing heap.

◆ mi_heap_get_backing()

mi_heap_t* mi_heap_get_backing ( )

Get the backing heap.

The backing heap is the initial default heap for a thread and always available for allocations. It cannot be destroyed or deleted except by exiting the thread.

◆ mi_heap_get_default()

mi_heap_t* mi_heap_get_default ( )

Get the default heap that is used for mi_malloc() et al.

Returns: The current default heap.

◆ mi_heap_malloc()

void* mi_heap_malloc	(	mi_heap_t *	heap,
		size_t	size
	)

Allocate in a specific heap.

See also: mi_malloc()

◆ mi_heap_mallocn()

void* mi_heap_mallocn	(	mi_heap_t *	heap,
		size_t	count,
		size_t	size
	)

Allocate count elements in a specific heap.

See also: mi_mallocn()

◆ mi_heap_new()

mi_heap_t* mi_heap_new ( )

Create a new heap that can be used for allocation.

◆ mi_heap_realpath()

char* mi_heap_realpath	(	mi_heap_t *	heap,
		const char *	fname,
		char *	resolved_name
	)

Resolve a file path name using a specific heap to allocate the result.

See also: mi_realpath()

◆ mi_heap_set_default()

mi_heap_t* mi_heap_set_default ( mi_heap_t * heap )

Set the default heap to use for mi_malloc() et al.

Parameters

heap	The new default heap.

Returns: The previous default heap.

◆ mi_heap_strdup()

char* mi_heap_strdup	(	mi_heap_t *	heap,
		const char *	s
	)

Duplicate a string in a specific heap.

See also: mi_strdup()

◆ mi_heap_strndup()

char* mi_heap_strndup	(	mi_heap_t *	heap,
		const char *	s,
		size_t	n
	)

Duplicate a string of at most length n in a specific heap.

See also: mi_strndup()

◆ mi_heap_zalloc()

void* mi_heap_zalloc	(	mi_heap_t *	heap,
		size_t	size
	)

Allocate zero-initialized in a specific heap.

See also: mi_zalloc()
