     DESCRIPTION
          Fork causes creation of a new process.  The new process
          (child process) is an exact copy of the calling process
          (parent process) except for the following:

               The child process has a unique process ID.

               The child process has a different parent process ID
               (i.e., the process ID of the parent process).

               The child process has its own copy of the parent's file
               descriptors.  Each of the child's file descriptors
               shares a common file pointer with the corresponding
               file descriptor of the parent.

               The child process's utime , " stime" , " cutime" , and
               cstime are set to 0 ; see times (2).

          Fork returns a value of 0 to the child process.

          Fork returns the process ID of the child process to the
          parent process.

          Fork will fail and no child process will be created if one
          or more of the following are true:

               The system-imposed limit on the total number of
               processes under execution would be exceeded.  [EAGAIN]

               The system-imposed limit on the total number of
               processes under execution by a single user would be
               exceeded.  [EAGAIN]

     RETURN VALUE

     RETURN VALUE
          Upon successful completion, fork returns a value of 0 to the
          child process and returns the process ID of the child
          process to the parent process.  Otherwise, a value of -1 is
          returned to the parent process, no child process is created,
          and errno is set to indicate the error.
