Name
stack_init
Synopsis
void stack_init(Stack *stack, void (*destroy)(void *data));
Return Value
None.
Description
Initializes the stack specified by
stack. This operation must be called
for a stack before the stack can be used with any other operation.
The destroy argument provides a way to
free dynamically allocated data when
stack_destroy is called. For example, if the
stack contains data dynamically allocated using
malloc, destroy
should be set to free to free the data as the
stack is destroyed. For structured data containing several
dynamically allocated members, destroy
should be set to a user-defined function that calls
free for each dynamically allocated member as
well as for the structure itself. For a stack containing data that
should not be freed, destroy should be
set to NULL.
