NAME
libcadmin — libc administration command
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 executed, 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 applications 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.
