Include dependency graph for n_crypto.h:

This graph shows which files directly or indirectly include this file:

Macros
#define	n_mathmod(__a, __b) ((__a % __b + __b) % __b)
	The % operator returns a result that adopts the sign of the dividend, a true mathematical modulus adopts the sign of the divisor.
