Function Documentation

size_t default_gt_pch_alloc_granularity

(

void

)

Default version of HOST_HOOKS_GT_PCH_GET_ADDRESS. Return the alignment required for allocating virtual memory. Usually this is the same as pagesize.

References limit.

void* default_gt_pch_get_address	(	size_t	size,
		int	fd
	)

Default version of HOST_HOOKS_GT_PCH_GET_ADDRESS when mmap is not present. Select no address whatsoever, and let gt_pch_save choose what it will with malloc, presumably.

int default_gt_pch_use_address	(	void *	base,
		size_t	size,
		int	fd,
		size_t	offset
	)

Default version of HOST_HOOKS_GT_PCH_USE_ADDRESS when mmap is not present. Allocate SIZE bytes with malloc. Return 0 if the address we got is the same as base, indicating that the memory has been allocated but needs to be read in from the file. Return -1 if the address differs, to relocation of the PCH file would be required.

void* mmap_gt_pch_get_address	(	size_t	,
		int
	)

int mmap_gt_pch_use_address	(	void *	,
		size_t	,
		int	,
		size_t
	)
