NAMEmalloc_get_state, malloc_set_state - record and restore state of malloc implementation
int malloc_set_state(void *state);
DESCRIPTIONThe malloc_get_state() function records the current state of all malloc(3) internal bookkeeping variables (but not the actual contents of the heap or the state of malloc_hook(3) functions pointers). The state is recorded in a system-dependent opaque data structure dynamically allocated via malloc(3), and a pointer to that data structure is returned as the function result. (It is the caller's responsibility to free(3) this memory.)
RETURN VALUEOn success, malloc_get_state() returns a pointer to a newly allocated opaque data structure. On error (for example, memory could not be allocated for the data structure), malloc_get_state() returns NULL.
CONFORMING TOThese functions are GNU extensions.
NOTESThese functions are especially useful when using this malloc(3) implementation as part of a shared library, and the heap contents are saved/restored via some other method. This technique is used by the GNU Emacs to implement its "dumping" function.
