Detailed Description

mi_ prefixed implementations of various Posix, Unix, and C++ allocation functions.

Defined for convenience as all redirect to the regular mimalloc API.

Function Documentation

mi__expand()

void * mi__expand	(	void *	p,
		size_t	newsize )

mi__posix_memalign()

int mi__posix_memalign	(	void **	p,
		size_t	alignment,
		size_t	size )

mi_aligned_alloc()

void * mi_aligned_alloc	(	size_t	alignment,
		size_t	size )

mi_aligned_offset_recalloc()

void * mi_aligned_offset_recalloc	(	void *	p,
		size_t	newcount,
		size_t	size,
		size_t	alignment,
		size_t	offset )

mi_aligned_recalloc()

void * mi_aligned_recalloc	(	void *	p,
		size_t	newcount,
		size_t	size,
		size_t	alignment )

mi_dupenv_s()

int mi_dupenv_s	(	char **	buf,
		size_t *	size,
		const char *	name )

mi_free_aligned()

void mi_free_aligned	(	void *	p,
		size_t	alignment )

Free an object that was allocated aligned.

Parameters

p	The pointer to the object (or NULL )
alignment	The requested alignment at the allocation. At this time just defers to mi_free() but it can be optimized in the future for aligned allocations.

mi_free_size()

void mi_free_size	(	void *	p,
		size_t	size )

Free a block that was allocated with a known size.

Parameters

p	The pointer that was allocated with size bytes (or NULL )
size	The size in bytes. v3: this can improve performance for objects with a size < MI_SMALL_SIZE_MAX() as it will use mi_free_small() internally. Always use this if possible. Note: it is not allowed to use mi_free_size() for aligned allocations, use mi_free_size_aligned() (mi_free()) instead.

mi_free_size_aligned()

mi_free_size_aligned()

void mi_free_size_aligned	(	void *	p,
		size_t	size,
		size_t	alignment )

Free an object that was allocated aligned.

Parameters

p	The pointer to the object (or NULL )
size	The size of the object as allocated.
alignment	The requested alignment at the allocation. This can be faster than using mi_free() for aligned allocations.

mi_free_size_nonnull()

void mi_free_size_nonnull	(	void *	p,
		size_t	size )

Free a non-NULL pointer that was allocated with a known size.

Parameters

p	The pointer that was allocated with size bytes (cannot be NULL !)
size	The size in bytes. v3: this can improve performance for objects with a size < MI_SMALL_SIZE_MAX() as it will use mi_free_small_nonnull() internally. Always use this if possible. Note: it is not allowed to use mi_free_size() for aligned allocations, use mi_free_size_aligned() (or mi_free()) instead.
