pxfsysconf(3F)

NAME
     PXFSYSCONF - Retrieves the value of configurable system variables

SYNOPSIS
     INTEGER NAME, IVAL, IERROR
     CALL PXFSYSCONF (name, ival, ierror)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     IEEE standard interface for FORTRAN 77

DESCRIPTION
     On IRIX systems, this routine is in libfortran.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.

     The PXFSYSCONF routine uses the sysconf() function to retrieve the
     current value for the name configurable system variable.

     When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
     UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
     kind unless documented otherwise.  On UNICOS and UNICOS/mk, default
     kind is KIND=8 for integer, real, complex, and logical arguments; on
     IRIX, the default kind is KIND=4.

     This routine has the following arguments:

     name    An input integer variable or array element containing the
             integer value of a symbolic constant for one of the following
             configurable system variables defined in POSIX Std. 1003.1,
             section 4.8.1.2:
                  ARG_MAX
                  CHILD_MAX
                  CLK_TCK
                  NGROUPS_MAX
                  OPEN_MAX
                  STREAM_MAX
                  TZNAME_MAX
                  _POSIX_JOB_CONTROL
                  _POSIX_SAVED_IDS
                  _POSIX_VERSION

             The integer value for each of these symbolic constants is
             retrieved through the use of PXFCONST or IPXFCONST.  The
             integer values may be combined through the use of a bitwise
             inclusive OR function.

     ival    An output integer variable that will contain the value of the
             system variable name.

     ierror  An output integer variable that contains zero if PXFSYSCONF
             was successful or nonzero if name is an invalid system
             variable.

EXAMPLES
     In this example, PXFSYSCONF will retrieve the value of the CLK_TCK
     system variable.

                program test
                integer ival, ierr, iclktck
                ival = 0
                iclktck = 0
                call pxfconst ('CLK_TCK',iclktck,ierr)
                if (ierr.ne.0) then
                   print *,'FAIL: error from pxfconst = ',ierr
                   goto 9999
                endif
                call pxfsysconf (iclktck, ival, ierr)
                if (ierr.ne.0) then
                   print *,'FAIL: error from pxfsysconf = ',ierr
                else
                   print *,'PASS: error from pxfsysconf = ',ierr
                endif
                print *, 'CLK_TCK=',ival
          9999  continue
                end
