Function Types for IDA

Need double underscore to init (__)

C = Const (is referring to the variable before it e.g. cC = const Char == Char const)
F = Function (what follows after are input params)
G = Return type (what follows after is return type)
P = Pointer
R = &
S = Signed
U = Unsigned
V = Volatile

c = char
f = float
i = int
l = long
s = short
v = void


Lesser used types:

b = bool
d = double
w = wchar_t
x = long long


Custom Types:

va_list_struct = void test(const char *format, ...)
