Member Data Documentation

int obstack::alignment_mask

Mask of alignment for each object.

unsigned obstack::alloc_failed

chunk alloc func returned 0

struct _obstack_chunk* obstack::chunk

address of current struct obstack_chunk

char* obstack::chunk_limit

address of char after current chunk

long obstack::chunk_size

preferred size to allocate chunks in

struct _obstack_chunk*(* obstack::chunkfun)(int)

User's fcn to allocate a chunk.

char* obstack::extra_arg

first arg for chunk alloc/dealloc funcs

void(* obstack::freefun)(void *)

User's function to free a chunk.

unsigned obstack::maybe_empty_object

There is a possibility that the current chunk contains a zero-length object. This prevents freeing the chunk if we allocate a bigger chunk to replace it.

char* obstack::next_free

where to add next char to current object

char* obstack::object_base

address of object we are building

PTR_INT_TYPE obstack::temp

Temporary for some macros.

unsigned obstack::use_extra_arg

chunk alloc/dealloc funcs take extra arg
