My reverse-engineering of a certain ELF thrown at me

iosuaccess.c

void (*mystery_func)(int a, int b); //Pointer, OSDynLoad?
void (*mystery_func2)(void*)
void another_mystery(void* a, void* b, int c, int d); //Built in to app
void possible_init_func(...); //Built in, a few bits missing
void yet_another_func(int possibly_not_used);

int ret, var1, var2, var3, var4; //var3 and var2 have not been set in this function before they are used, var4 isn't actually in memory

var1 = 0; //var1 might be global

ret = possible_init_func(&var1, other pointers);

if (ret >= 0) { //The variables are checked in this order
	if (var1 != 0) {
		if (var3 != 0) {

					mystery_func(0, 0|0xF2CC);
					if (var2 == 0) {

				}
			}
			var2 = 1;
			var4 = another_mystery(&var1);

						var4 = 0x578;

					//ret is compared up here
					var4 = ret - var4;
