pxfunlink(3F)

NAME
     PXFUNLINK - Removes a directory entry

SYNOPSIS
     CHARACTER*n path
     INTEGER ilen, ierror
     CALL PXFUNLINK(path, ilen, ierror)

STANDARDS
     IEEE standard interface for FORTRAN 77

DESCRIPTION
     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 PXFUNLINK routine uses the unlink(2) system call to remove a
     directory entry for the named file.

     All arguments must be of default kind unless documented otherwise.  On
     IRIX systems, the default kind is KIND=4.

     The following is a list of valid arguments for this routine:

     path      An input character variable or array element containing the
               name of a file.

     ilen      An input integer variable containing the length of path in
               characters.  If ilen is zero, all trailing blanks are
               removed before calling unlink.

     ierror    An output integer variable that contains a zero if the named
               file was removed.

     In addition to the errors returned by the unlink(2) system call,
     PXFUNLINK may return the following errors:

     EINVAL       If ilen < 0 or ilen > LEN(path).

     ENOMEM       If PXFUNLINK is unable to obtain memory to copy path.

NOTES
     The PXF_DEFINITIONS module can be used by Fortran 90 users to enable
     caller-callee interface checking.

EXAMPLES
          program test
          character*(12) path
          integer ilen, ierr
          path = 'testfile'
          ilen = 0
          call pxfunlink(path,ilen,ierr)
          if (ierr.ne.0) then
              print *,'FAIL: error from pxfunlink = ',ierr
          else
              print *,'PASS: No error from pxfunlink = '
          endif
          end
