Michael, We should update man3/sigvec.3 to indicate it can no longer be used on Linux with glibc 2.21. The sigvec function was removed in glibc 2.21. https://sourceware.org/glibc/wiki/Release/2.21#Packaging_Changes Cheers, Carlos. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
