-The value of the semaphore is never negative, even if there are threads blocked
-on the semaphore.
-POSIX is somewhat ambiguous in its wording with regard to
-what the value of the semaphore should be if there are blocked waiting threads,
-but this behavior is conformant, given the wording of the specification.

-.Dt SEM_INIT 3
-.Os
-.Sh NAME
-.Nm sem_init
-.Nd initialize an unnamed semaphore
-.Sh LIBRARY
-.Lb libpthread
-.Sh SYNOPSIS
-.In semaphore.h
-.Ft int
-.Fn sem_init "sem_t *sem" "int pshared" "unsigned int value"
-.Sh DESCRIPTION
-The
-.Fn sem_init
-function initializes the unnamed semaphore pointed to by
-.Fa sem
-to have the value
-.Fa value .
-A non-zero value for
-.Fa pshared
-specifies a shared semaphore that can be used by multiple processes, which this
-implementation is not capable of.
-.Pp
-Following a successful call to
-.Fn sem_init ,
-.Fa sem
-can be used as an argument in subsequent calls to
-.Fa sem_wait ,
-.Fa sem_trywait ,
-.Fa sem_post ,
-and
-.Fa sem_destroy .
-.Fa sem
-is no longer valid after a successful call to
-.Fa sem_destroy .
-.Sh RETURN VALUES
-.Rv -std sem_init
-.Sh ERRORS
-.Fn sem_init
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-.Fa value
-exceeds SEM_VALUE_MAX.
-.It Bq Er ENOSPC
-Memory allocation error.
-.It Bq Er EPERM
-Unable to initialize a shared semaphore.
-.El
-.Sh SEE ALSO
-.Xr sem_destroy 3 ,
-.Xr sem_post 3 ,
-.Xr sem_trywait 3 ,
-.Xr sem_wait 3
-.Sh STANDARDS
-.Fn sem_init
-conforms to
-.St -p1003.1-96 .
-.Pp
-This implementation does not support shared semaphores, and reports this fact
-by setting
-.Va errno
-to
-.Er EPERM .
-This is perhaps a stretch of the intention of POSIX, but is
-compliant, with the caveat that
-.Fn sem_init
-always reports a permissions error when an attempt to create a shared semaphore
-is made.
