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 Creating Obstacks.

void *obstack_alloc (struct obstack *obstack_ptr, size_t size)
Allocate an object of size uninitialized bytes. See section Allocation in an Obstack.

void *obstack_copy (struct obstack *obstack_ptr, void *address, size_t size)
Allocate an object of size bytes, with contents copied from address. See section Allocation in an Obstack.

void *obstack_copy0 (struct obstack *obstack_ptr, void *address, size_t 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 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 Freeing Objects in an Obstack.

void obstack_blank (struct obstack *obstack_ptr, size_t size)
Add size uninitialized bytes to a growing object. See section Growing Objects.

void obstack_grow (struct obstack *obstack_ptr, void *address, size_t size)
Add size bytes, copied from address, to a growing object. See section Growing Objects.

void obstack_grow0 (struct obstack *obstack_ptr, void *address, size_t size)
Add size bytes, copied from address, to a growing object, and then add another byte containing a null character. See section Growing Objects.

void obstack_1grow (struct obstack *obstack_ptr, char data_char)
Add one byte containing data_char to a growing object. See section Growing Objects.

void *obstack_finish (struct obstack *obstack_ptr)
Finalize the object that is growing and return its permanent address. See section Growing Objects.

size_t obstack_object_size (struct obstack *obstack_ptr)
Get the current size of the currently growing object. See section Growing Objects.

void obstack_blank_fast (struct obstack *obstack_ptr, size_t size)
Add size uninitialized bytes to a growing object without checking that there is enough room. See section 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 Extra Fast Growing Objects.

size_t obstack_room (struct obstack *obstack_ptr)
Get the amount of room now available for growing the current object. See section 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 Alignment of Data in Obstacks.

size_t obstack_chunk_size (struct obstack *obstack_ptr)
The size for allocating chunks. This is an lvalue. See section Obstack Chunks.

void *obstack_base (struct obstack *obstack_ptr)
Tentative starting address of the currently growing object. See section Status of an Obstack.

void *obstack_next_free (struct obstack *obstack_ptr)
Address just after the end of the currently growing object. See section Status of an Obstack.
