      * PARAMETERS
      *      sem
      * 	     pointer to an instance of sem_t
      *
      *      pshared
      * 	     if zero, this semaphore may only be shared between
      * 	     threads in the same process.
      * 	     if nonzero, the semaphore can be shared between
      * 	     processes
      *
      *      value
      * 	     initial value of the semaphore counter
      *
      * DESCRIPTION
      *      This function initializes a semaphore. The
      *      initial value of the semaphore is set to 'value'.
      *
      * RESULTS
      * 	     0		     successfully created semaphore,
      * 	     -1 	     failed, error in errno
      * ERRNO
      * 	     EINVAL	     'sem' is not a valid semaphore,
      * 	     ENOSPC	     a required resource has been exhausted,
      * 	     ENOSYS	     semaphores are not supported,
      * 	     EPERM	     the process lacks appropriate privilege
