Macro Definition Documentation

◆ memarea_drop_all

#define memarea_drop_all ( area )

Value:

  do {                                          \
    memarea_drop_all_(area);                    \
    (area) = NULL;                              \
  } while (0)

Free area, invalidating all pointers returned from memarea_alloc() and friends for this area

Additionally, set area to NULL.

Function Documentation

◆ memarea_alloc()

void* memarea_alloc	(	memarea_t *	area,
		size_t	sz
	)

Return a pointer to a chunk of memory in area of at least sz bytes. sz should be significantly smaller than the area's chunk size, though we can deal if it isn't.

◆ memarea_alloc_zero()

void* memarea_alloc_zero	(	memarea_t *	area,
		size_t	sz
	)

As memarea_alloc(), but clears the memory it returns.

Definition at line 248 of file memarea.c.

◆ memarea_assert_ok()

void memarea_assert_ok ( memarea_t * area )

Assert that area is okay.

Definition at line 305 of file memarea.c.

◆ memarea_clear()

void memarea_clear ( memarea_t * area )

Forget about having allocated anything in area, and free some of the backing storage associated with it, as appropriate. Invalidates all pointers returned from memarea_alloc() for this area.

Definition at line 178 of file memarea.c.

◆ memarea_drop_all_()

void memarea_drop_all_ ( memarea_t * area )

Free area, invalidating all pointers returned from memarea_alloc() and friends for this area

Definition at line 163 of file memarea.c.

◆ memarea_get_stats()

void memarea_get_stats	(	memarea_t *	area,
		size_t *	allocated_out,
		size_t *	used_out
	)

Set allocated_out to the number of bytes allocated in area, and used_out to the number of bytes currently used.

Definition at line 289 of file memarea.c.

◆ memarea_memdup()

void* memarea_memdup	(	memarea_t *	area,
		const void *	s,
		size_t	n
	)

As memdup, but returns the memory from area.

Definition at line 257 of file memarea.c.

Referenced by cdline_linecpy(), and memarea_strdup().

◆ memarea_new()

memarea_t* memarea_new ( void )

Allocate and return new memarea.

◆ memarea_owns_ptr()

int memarea_owns_ptr	(	const memarea_t *	area,
		const void *	p
	)

Return true iff p is in a range that has been returned by an allocation from area.

Definition at line 194 of file memarea.c.

◆ memarea_strdup()

char* memarea_strdup	(	memarea_t *	area,
		const char *	s
	)

As strdup, but returns the memory from area.

Definition at line 266 of file memarea.c.

◆ memarea_strndup()

char* memarea_strndup	(	memarea_t *	area,
		const char *	s,
		size_t	n
	)

As strndup, but returns the memory from area.
