#include <complex.h>

double complex ccosh(double complex z);
float complex ccoshf(float complex z);
long double complex ccoshl(long double complex z);

Link with -lm.

The complex hyperbolic cosine function is defined as:



    ccosh(z) = (exp(z)+exp(-z))/2

These functions first appeared in glibc in version 2.1.
