pxfunlink(3F)

NAME
     PXFUNLINK - Removes a directory entry

SYNOPSIS
     CHARACTER*n path
     INTEGER ilen, ierror
     CALL PXFUNLINK(path, ilen, 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
     7.2 F77 compiler.

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

     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.

     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.

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
