pxfischr(3F)

NAME
     PXFISCHR - Tests for character special file

SYNOPSIS
     LOGICAL FUNCTION PXFISCHR(m)
     INTEGER m

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 logical function PXFISCHR checks if a file is a character special
     file. The argument m should be supplied by the st_mode component of
     the stat structure used by the PXFSTAT(3F) routine.

     When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
     UNICOS, UNICOS/mk, or IRIX, 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.

     The following is a valid argument for this routine:

     m    An integer input variable containing the file mode.

     If the file is a character special file, PXFISCHR returns a logical
     true, otherwise a logical false is returned.

EXAMPLES
     In this example, PXFSTAT is called on /dev/tty, which should be a
     character special file. After PXFINTGET(3F) returns the mode of
     /dev/tty, PXFISCHR is called to check the mode of /dev/tty.

     program pxftest
     integer jstat,ierror,mode
     logical pxfischr

     CALL PXFSTRUCTCREATE('stat',jstat,ierror)
     CALL PXFSTAT('/dev/tty',0,jstat,ierror)
     CALL PXFINTGET(jstat,'st_mode', mode, ierror)
      if (PXFISCHR(mode) .eqv. .TRUE.) then
         print *,'/dev/tty is a character special file.'
      else
         print *,'/dev/tty should be a character special file, but is not.'
      endif
     end

     This program may display:

          /dev/tty is a character special file.
