modpath(2) System Calls Manual modpath(2)
NAME
modpath - change global search path for dynamically loadable kernel modules
SYNOPSIS
DESCRIPTION
allows processes with appropriate privilege to modify the global search path used to locate object files for dynamically loadable kernel
modules. The search path modifications take effect immediately and affect all subsequent loads for all users on the system.
pathname may be either a colon-separated list of absolute path names or NULL. If the former, these path names represent directories which
should be searched for all autoloads of loadable kernel modules and for demand loads (see modload(2)) where the module is given by a simple
file name. This list of directories will be prepended to the existing list of directories and so will be searched before any directories
given in previous calls to and before the default location which is always searched last. The directories do not have to exist on the sys-
tem at the time is called, or when a load actually takes place. If pathname is equal to NULL, the global search path is set back to its
initial default value,
Notes
is currently implemented as a macro. Module search path is not persistent across boots.
Security Restrictions
is restricted to superuser processes or privileged processes. A privileged process requires the privilege to execute the system call.
See privileges(5) for more information about the privilege.
RETURN VALUE
On success, returns 0, otherwise it returns -1 and sets to indicate the error.
ERRORS
fails if one or more of the following are true:
The list of directories specified by pathname is malformed.
The Dynamically Loadable Kernel Module feature is not initialized.
pathname
is more than characters long.
The caller is not a superuser process or a privileged process.
