When the below code sample is compiled: * on linux - there is one error too few arguments to function call waitid * on freebsd - there are two errors (a) unknown type name 'siginfo_t' (b) too few arguments to function call waitid I'm not sure if it's a bug in the standard, linux implementation, or freebsd implementation. But it would be nice, if both linux & freebsd implementations interpreted the standard the same, i.e. "#include <sys/wait.h> is enough to call waitid()" >How-To-Repeat: #include <sys/wait.h> siginfo_t info; int main(){ waitid(); return 0; } >Fix: <sys/wait.h> header should include <signal.h> header. >Release-Note: >Audit-Trail: >Unformatted:
