NAMEPXFUNLINK - 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
