https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212033 --- Comment #4 from Ingo Schwarze <schwarze@usta.de> --- (In reply to Andrey Chernov from comment #2) > Moreover, the whole code is broken for empty input, > it returns NULL instead of pointer to L'\0' No, the code is correct in *that* respect. Empty input means we are at EOF right away. At EOF, the function is docume= nted to return NULL without setting errno or the stdio error indicator. Returni= ng L"" means there is an empty line, and an empty line is not the same as empty input. For example: Empty line: Reading from the pipe 'printf "\n" |' returns L"" to the first call of fgetwln(3) and NULL to the second. Empty input: Reading from the pipe 'printf "" |' returns NULL to the first call of fgetwln(3). --=20 You are receiving this mail because: You are the assignee for the bug.=
