Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
|| /* Since glibc 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
DESCRIPTIONThese functions return the sine of x, where x is given in radians.
RETURN VALUEOn success, these functions return the sine of x.
If x is a NaN, a NaN is returned.
If x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned.
ERRORSSee 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
- errno is set to EDOM (but see BUGS). An invalid floating-point exception (FE_INVALID) is raised.
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).

CONFORMING TOC99, POSIX.1-2001, POSIX.1-2008.
The variant returning double also conforms to SVr4, 4.3BSD, C89.
BUGSBefore version 2.10, the glibc implementation did not set errno to EDOM when a domain error occurred.
