sincos, sincosf, sincosl - calculate sin and cos simultaneously
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <math.h> void sincos(double x, double *sin, double *cos); void sincosf(float x, float *sin, float *cos); void sincosl(long double x, long double *sin, long double *cos); Link with -lm.
Several applications need sine and cosine of the same angle x. These functions compute both at the same time, and store the results in *sin and *cos. If x is a NaN, a NaN is returned in *sin and *cos. If x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned in *sin and *cos.
These functions return void.
See math_error(7) for information on how to determine whether an error has occurred when calling these functions. The following errors can occur: Domain error: x is an infinity An invalid floating-point exception (FE_INVALID) is raised. These functions do not set errno.
These functions first appeared in glibc in version 2.1.

These functions are GNU extensions.
