NAME
libcadmin - libc administration command
SYNOPSIS
/usr/sbin/libcadmin
DESCRIPTION
The libcadmin command is used to perform administrative functions for
libc. Currently the only
function that the command performs is to replace the shared 32-bit PA-RISC2.0 library in
/usr/lib/libc.2
with the shared 32-bit PA-RISC1.1 version of that library.
There are no required arguments or options used with this command. The
/usr/lib/libc.a
archive
library and the
libc.sl symbolic link are unaffected by the
libcadmin command.
During the system installation process, the shared 32-bit PA-RISC1.1 library is copied into
/usr/lib/pa11_32
. This library is the same as the PA-RISC2.0 library except that it was built with
different compiler options. The PA-RISC2.0 library provides much higher performance than the PA-
RISC1.1 library. However, if the system administrator desires to have the PA-RISC1.1 library installed
instead,
libcadmin allows the system administrator to accomplish this task. When
libcadmin is exe-
cuted, the PA-RISC2.0 library is stored in
/usr/lib/pa20_32
and the PA-RISC1.1 library is copied
into
/usr/lib/libc.2.
It is recommended that the system be re-booted after executing the
libcadmin command so that applica-
tions which are linked shared against libc will use the shared 32-bit PA-RISC1.1 version of that library.
Once the command is executed, the only way to put the PA-RISC2.0 library back in place is to re-install the
operating system.
The libcadmin command can only be executed by a user with superuser privileges.
ERRORS
Multiple executions of the command will result in an error message indicating the PA-RISC1.1 library is
already installed.
Executing this command on a PA-RISC1.1 machine will result in an error message indicating the PA-
RISC1.1 library is already installed.
RETURN VALUES
Upon successful completion, libcadmin returns zero (0). Otherwise a one (1) is returned.
