setjmp
Saves its calling environment in its jmp_buf argument, for later use by the
longjmp
function.
Synopsis
#include
int setjmp(jmp_buf env);
Returns
If the return is from a direct invocation, the
setjmp
function returns the value zero. If the
return is from a call to the
longjmp
function, the
setjmp
function returns a nonzero
value.
Example
int i;
jmp_buf env;
i=setjmp(env);
longjmp(env, i);
sin, sinf
Computes the sine of x (measured in radians). A large magnitude argument can yield a
result with little or no significance.
Synopsis
#include
double sin(double x);
float sinf(float x);
Returns
The sine value.
Example
double x=1.24;
double y;
y=sin(x);
