3.11 Summary of Obstack Functions
Here is a summary of all the functions associated with obstacks. Each
takes the address of an obstack (struct obstack *
) as its first
argument.
void obstack_init (struct obstack *obstack-ptr)
- Initialize use of an obstack. See section 3.1 Creating Obstacks.
void *obstack_alloc (struct obstack *obstack-ptr, int size)
- Allocate an object of size uninitialized bytes.
See section 3.3 Allocation in an Obstack.
void *obstack_copy (struct obstack *obstack-ptr, void *address, int size)
- Allocate an object of size bytes, with contents copied from
address. See section 3.3 Allocation in an Obstack.
void *obstack_copy0 (struct obstack *obstack-ptr, void *address, int size)
- Allocate an object of size+1 bytes, with size of them copied
from address, followed by a null character at the end.
See section 3.3 Allocation in an Obstack.
void obstack_free (struct obstack *obstack-ptr, void *object)
- Free object (and everything allocated in the specified obstack
more recently than object). See section 3.4 Freeing Objects in an Obstack.
void obstack_blank (struct obstack *obstack-ptr, int size)
- Add size uninitialized bytes to a growing object.
See section 3.6 Growing Objects.
void obstack_grow (struct obstack *obstack-ptr, void *address, int size)
- Add size bytes, copied from address, to a growing object.
See section 3.6 Growing Objects.
void obstack_grow0 (struct obstack *obstack-ptr, void *address, int size)
- Add size bytes, copied from address, to a growing object,
and then add another byte containing a null character. See section 3.6 Growing Objects.
void obstack_1grow (struct obstack *obstack-ptr, char data-char)
- Add one byte containing data-char to a growing object.
See section 3.6 Growing Objects.
void *obstack_finish (struct obstack *obstack-ptr)
- Finalize the object that is growing and return its permanent address.
See section 3.6 Growing Objects.
int obstack_object_size (struct obstack *obstack-ptr)
- Get the current size of the currently growing object. See section 3.6 Growing Objects.
void obstack_blank_fast (struct obstack *obstack-ptr, int size)
- Add size uninitialized bytes to a growing object without checking
that there is enough room. See section 3.7 Extra Fast Growing Objects.
void obstack_1grow_fast (struct obstack *obstack-ptr, char data-char)
- Add one byte containing data-char to a growing object without
checking that there is enough room. See section 3.7 Extra Fast Growing Objects.
int obstack_room (struct obstack *obstack-ptr)
- Get the amount of room now available for growing the current object.
See section 3.7 Extra Fast Growing Objects.
int obstack_alignment_mask (struct obstack *obstack-ptr)
- The mask used for aligning the beginning of an object. This is an
lvalue. See section 3.9 Alignment of Data in Obstacks.
int obstack_chunk_size (struct obstack *obstack-ptr)
- The size for allocating chunks. This is an lvalue. See section 3.10 Obstack Chunks.
void *obstack_base (struct obstack *obstack-ptr)
- Tentative starting address of the currently growing object.
See section 3.8 Status of an Obstack.
void *obstack_next_free (struct obstack *obstack-ptr)
- Address just after the end of the currently growing object.
See section 3.8 Status of an Obstack.
