Function Documentation

default_gt_pch_alloc_granularity()

size_t default_gt_pch_alloc_granularity ( void )

extern

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

default_gt_pch_get_address()

void * default_gt_pch_get_address ( size_t size, int fd )

extern

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.   

References NULL.

default_gt_pch_use_address()

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

extern

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.   

mmap_gt_pch_get_address()

void * mmap_gt_pch_get_address ( size_t , int  )

extern

mmap_gt_pch_use_address()

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

extern
