WebAug 5, 2010 · In C, memcmp () is almost always used for comparisons of binary data. Its API specifies that it compares two fixed-length buffers and returns the difference between them or zero if they are identical. In most implementations, memcmp () exits as soon as a difference is found in the two buffers. WebThe CRYPTO_memcmp function compares the lenbytes pointed to by aand bfor equality. It takes an amount of time dependent on len, but independent of the contents of the memory regions pointed to by aand b. RETURN VALUES¶ CRYPTO_memcmp()returns 0 if the memory regions are equal and nonzero otherwise. NOTES¶ cupang west
