sys/ipc.h is fine.

--------------------------------------------

mman.h doesn't declare the following optional functions:

int mlock(const void *, size_t);
int mlockall(int);
int munlock(const void *, size_t);
int munlockall(void);
int posix_mem_offset(const void *restrict, size_t, off_t *restrict, size_t *restrict, int *restrict);
int posix_typed_mem_get_info(int, struct posix_typed_mem_info *);
int posix_typed_mem_open(const char *, int, int);

and doesn't define the following symbolic constants:

flags for mlockall()
MCL_CURRENT
MCL_FUTURE

flags for posix_typed_mem_open()
POSIX_TYPED_MEM_ALLOCATE  
POSIX_TYPED_MEM_ALLOCATE_CONTIG 
POSIX_TYPED_MEM_MAP_ALLOCATABLE

--------------------------------------------

sys/msg.h is fine.

--------------------------------------------

resource.h doesn't declare the following mandatory functions (as noted in the header):

int setpriority(int, id_t, int);
int getpriority(int, id_t);

The symbolic constants for these, however, are defined.

--------------------------------------------

sys/select.h is fine.

--------------------------------------------

sys/sem.h is fine.

--------------------------------------------

sys/shm.h is missing altogether.

--------------------------------------------

sys/socket.h

sa_family_t type-def is missing.

sa_family member of sockaddr struct should be of type sa_family_t.
ss_family member of sockaddr_storage struct should be of type sa_family_t.

--------------------------------------------

sys/stat.h doesn't declare the following functions:

int mknod(const char *, mode_t, dev_t);
int mknodat(int, const char *, mode_t, dev_t);

both of which are marked as "XSI" in the standard.

--------------------------------------------

sys/statvfs.h is fine.

--------------------------------------------

sys/time.h is fine.

--------------------------------------------

sys/times.h is fine.

--------------------------------------------

sys/types.h is fine.

--------------------------------------------

sys/uio.h is fine.

--------------------------------------------

sys/un.h

sun_family member of sockaddr_un struct should be of type sa_family_t
(see note of type-def ommision in sys/socket.h above).

--------------------------------------------

sys/utsname.h is fine.

--------------------------------------------

sys/wait.h doesn't declare (as noted in the header):

int waitid(idtype_t, id_t, siginfo_t *, int);

and doesn't define its idtype_t enum (it's there, but commented out).
