PXFCHROOT - Changes the root directory to a specified directory
CHARACTER*n path
INTEGER ilen, ierror
CALL PXFCHROOT(path, ilen, ierror)
UNICOS, UNICOS/mk, and IRIX systems
IEEE standard interface for FORTRAN 77
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 PXFCHROOT subroutine uses the chroot(2) system call to change the
root directory to the specified directory.
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 subroutine:
path Input character variable or array element containing the
name of a file.
ilen Input integer variable containing the length of path in
characters. If ilen is zero, all trailing blanks are
removed before calling chroot().
ierror Output integer variable that contains zero if the root
directory was changed to the directory specified by path or
nonzero if the root directory was not changed.
In addition to the errors returned by the chroot(2) system call,
PXFCHROOT may return the following errors:
EINVAL If ilen is less than 0 or if ilen is greater than LEN(path)
ENOMEM If PXFCHROOT is unable to obtain memory to copy path
program test
character*(12) path
integer ilen, ierr
path = '/dir/test'
ilen = 0
call pxfchroot(path,ilen,ierr)
if (ierr.ne.0) then
print *,'FAIL: error from pxfchroot = ',ierr
else
print *,'PASS: No error from pxfchroot'
endif
end
