View official documentation
Purpose:
Extract the lower 32-bit integer from a 64-bit MMX register and copy it to a CPU register or memory location. The upper 32 bits of the source MMX register are ignored and discarded.
Result:
int
Example:
#include <mmintrin.h>
#include <stdio.h>
int main() {
__m64 a = _mm_set_pi32(123456789, 42);
int r = _m_to_int(a);
printf("%d\n", r);
_mm_empty();
return 0;
