17 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
18
19 sinf(), sinl():
20 _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
21 || /* Since glibc 2.19: */ _DEFAULT_SOURCE
22 || /* Glibc <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
23
25 These functions return the sine of x, where x is given in radians.
26
28 On success, these functions return the sine of x.
29
30 If x is a NaN, a NaN is returned.
31
32 If x is positive infinity or negative infinity, a domain error occurs,
33 and a NaN is returned.
34
36 See math_error(7) for information on how to determine whether an error
37 has occurred when calling these functions.
38
39 The following errors can occur:
40
41 Domain error: x is an infinity
42 errno is set to EDOM (but see BUGS). An invalid floating-point
43 exception (FE_INVALID) is raised.

58 The variant returning double also conforms to SVr4, 4.3BSD, C89.
59
61 Before version 2.10, the glibc implementation did not set errno to EDOM
62 when a domain error occurred.
