-.Dt SEMGET 2
-.Os
-.Sh NAME
-.Nm semget
-.Nd obtain a semaphore id
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/sem.h
-.Ft int
-.Fn semget "key_t key" "int nsems" "int flag"
-.Sh DESCRIPTION
-Based on the values of
-.Fa key
-and
-.Fa flag ,
-.Fn semget
-returns the identifier of a newly created or previously existing
-set of semaphores.
-.\"
-.\" This is copied verbatim from the shmget manpage.  Perhaps
-.\" it should go in a common manpage, such as .Xr ipc 2
-.\"
-The key
-is analogous to a filename: it provides a handle that names an
-IPC object.
-There are three ways to specify a key:
-.Bl -bullet
-.It
-IPC_PRIVATE may be specified, in which case a new IPC object
-will be created.
-.It
-An integer constant may be specified.
-If no IPC object corresponding
-to
-.Fa key
-is specified and the IPC_CREAT bit is set in
-.Fa flag ,
-a new one will be created.
-.It
-The
-.Xr ftok 3
-function
-may be used to generate a key from a pathname.
-.El
-.\"
-.\" Likewise for this section, except SHM_* becomes SEM_*.
-.\"
-.Pp
-The mode of a newly created IPC object is determined by ORing these constants
-into the
-.Fa flag
-argument:
-.Bl -tag -width 0000
-.It Dv 0400
-Read access for user.
-.It Dv 0200
-Alter access for user.
-.It Dv 0040
-Read access for group.
-.It Dv 0020
-Alter access for group.
-.It Dv 0004
-Read access for other.
-.It Dv 0002
-Alter access for other.
-.El
-.Pp
-If a new set of semaphores is being created,
-.Fa nsems
-is used to indicate the number of semaphores the set should contain.
-Otherwise,
-.Fa nsems
-may be specified as 0.
-.Sh RETURN VALUES
-The
-.Fn semget
-system call
-returns the id of a semaphore set if successful; otherwise, -1
-is returned and
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The
-.Fn semget
-system call
-will fail if:
-.Bl -tag -width Er
-.\" ipcperm could fail (we are opening to read and write, as it were)
-.It Bq Er EACCES
-Access permission failure.
-.\"
-.\" sysv_sem.c is quite explicit about these, so I'm pretty sure
-.\" this is accurate
-.\"
-.It Bq Er EEXIST
-IPC_CREAT and IPC_EXCL were specified, and a semaphore set
-corresponding to
-.Fa key
-already exists.
-.It Bq Er EINVAL
-The number of semaphores requested exceeds the system imposed maximum
-per set.
-.It Bq Er EINVAL
-A semaphore set corresponding to
-.Fa key
-already exists and contains fewer semaphores than
-.Fa nsems .
-.It Bq Er EINVAL
-A semaphore set corresponding to
-.Fa key
-does not exist and
-.Fa nsems
-is 0 or negative.
-.It Bq Er ENOSPC
-Insufficiently many semaphores are available.
-.It Bq Er ENOSPC
-The kernel could not allocate a
-.Fa "struct semid_ds" .
-.It Bq Er ENOENT
-No semaphore set was found corresponding to
-.Fa key ,
-and IPC_CREAT was not specified.
