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. This
function computes both at the same time, and stores the results in *sin
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.
Multithreading (see pthreads(7))
The sincos(), sincosf(), and sincosl() functions are thread-safe.
This function is a GNU extension.
