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 Creating Obstacks.

void *obstack_alloc (struct obstack *obstack-ptr, int size)

Allocate an object of size uninitialized bytes. See 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 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 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 Freeing Obstack Objects.

void obstack_blank (struct obstack *obstack-ptr, int size)

Add size uninitialized bytes to a growing object. See Growing Objects.

void obstack_grow (struct obstack *obstack-ptr, void *address, int size)

Add size bytes, copied from address, to a growing object. See 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 Growing Objects.

void obstack_1grow (struct obstack *obstack-ptr, char data-char)

Add one byte containing data-char to a growing object. See Growing Objects.

void *obstack_finish (struct obstack *obstack-ptr)

Finalize the object that is growing and return its permanent address. See Growing Objects.

int obstack_object_size (struct obstack *obstack-ptr)

Get the current size of the currently growing object. See 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 Extra Fast Growing.

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 Extra Fast Growing.

int obstack_room (struct obstack *obstack-ptr)

Get the amount of room now available for growing the current object. See Extra Fast Growing.

int obstack_alignment_mask (struct obstack *obstack-ptr)

The mask used for aligning the beginning of an object. This is an lvalue. See Obstacks Data Alignment.

int obstack_chunk_size (struct obstack *obstack-ptr)

The size for allocating chunks. This is an lvalue. See Obstack Chunks.

void *obstack_base (struct obstack *obstack-ptr)

Tentative starting address of the currently growing object. See Status of an Obstack.

void *obstack_next_free (struct obstack *obstack-ptr)

Address just after the end of the currently growing object. See Status of an Obstack.
