= SDL_MostSignificantBitIndex32 = Use this function to get the index of the most significant (set) bit in a 32-bit number. This is also the same as the base 2 logarithm of the number. == Syntax == int SDL_MostSignificantBitIndex32(Uint32 x) == Function Parameters == {| |'''x''' |the number to find the MSB of |} == Return Value == Returns the index of the most significant bit of x, or -1 if x is 0. == Code Examples == #include "SDL_bits.h" if (bitmask) { int index = SDL_MostSignificantBitIndex32(bitmask); } ---- [[CategoryAPI]], [[CategoryBits]]
