https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224300 Bug ID: 224300 Summary: sys/sem.h improperly declares union semun Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: brooks@FreeBSD.org sys/sem.h declares union semun imporpertly. According to the POSIX manpage= , it should be declared by the application if required: > The semctl() function provides a variety of semaphore control operations = as > specified by cmd. The fourth argument is optional and depends upon the > operation requested. If required, it is of type union semun, which the > application shall explicitly declare: >=20 > union semun { > int val; > struct semid_ds *buf; > unsigned short *array; > } arg; union semun is used in the kernel so the declaration should be moved under = an #ifdef _KERNEL and an exprun should be performed. It looks like configure scripts commonly handle this case so it may change code, but shouldn't break much. --=20 You are receiving this mail because: You are the assignee for the bug.=
