Hi, >> bzero is deprecated by POSIX.1-2001, removed by POSIX.1-2008, and on glibc >> implementation now calls memset (previously some architecture added ifunc >> redirection to optimized bzero to avoid the extra function call, it was >> removed from all architectures). >> >> Also, GCC for some time also replaces bzero with memset so there is no gain >> in actually call bzero (check glibc commit 9403b71ae97e3f1a91c796ddcbb4e6f044434734). Agreed, there is no benefit from using it, and certainly no reason to try to undo its removal. We should promote standards, not try to subvert them... A more productive way would be to propose new functions to the C/C++ committees. > In addition, gcc -Wall warns if you mistakenly pass 0 as memset's 3rd > arg, which undercuts the argument that bzero avoids silly mistakes. Also I think GCC should give a deprecated/obsolete warning (or perhaps error?) when using bzero, bcmp, bcopy, index, rindex etc so people can start removing the few remaining uses from ancient code.
