ishell(3F)

NAME
     ISHELL - Executes a shell command

SYNOPSIS
     ISTAT = ISHELL(command)

DESCRIPTION
     This routine is in libffio.so which is linked by default when
     compiling programs with the MIPSpro 7 Fortran 90 compiler or when
     compiling programs with the -craylibs option to the MIPSpro F77
     compiler.

     ISHELL executes a shell command.  ISHELL has the following argument:

     command   Command to be given to the shell of type character.

     ISHELL passes command to the shell sh(1) as input, as if command were
     entered at a terminal.

RETURN VALUES
     ISHELL returns the termination status filled in by the waitpid(2)
     system call, which is used to wait for the child shell process.
     Unless the command was interrupted by a signal, its exit status is
     contained in bits 8 through 15 (bit 0 being the least significant bit)
     of the value returned by ISHELL (see the waitpid(2) man page for more
     information).  However, if any errors occur in running the shell or
     collecting its exit status, ISHELL returns a negative number; this
     number is the negative value of errno corresponding to the error.

EXAMPLES
                WRITE(TPMNT,500) DTV, XDT, VOL, XVOL, DSN, PDN, MBSV
                CALL ISHELL(TPMNT)
           500  FORMAT('tpmnt -l sl -F U -T -g ',a6,' -x ',a6,
               +       '-v ',a6,'=',a6,' -P ',a8,' -f ',a, ' -b ',a)
