int lfds610_stack_push( struct lfds610_stack_state *ss, void *user_data );


struct lfds610_stack_state *ss

A stack state as allocated by lfds610_stack_new.

void *user_data

A void pointer of user data which will be pushed onto the stack.

Return Value

The return value is 1 upon successful push, 0 upon failure. Failure occurs only when the stack has exhausted its freelist of elements. In this case, the user can call lfds610_stack_guaranteed_push, which will allocate a new element and push using that. Remember however that the stack can never shrink, so any such call will permanently increase the size of the stack by one element.
