modpath(2) modpath(2)

NAME

modpath - change global search path for dynamically loadable kernel modules

SYNOPSIS

#include <sys/mod.h>

int modpath(const char *

pathname );

DESCRIPTION

modpath allows users 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 pathnames 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 direc-

tories will be prepended to the existing list of directories and so will be searched before any directories

given in previous calls to

modpath and before the default location which is always searched last. The

directories do not have to exist on the system at the time

modpath 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,

/usr/conf/mod

Notes

modpath is currently implemented as a macro. Module search path is not persistent across boots.

RETURN VALUE

On success,

modpath returns 0, otherwise it returns -1 and sets errno to indicate the error.

ERRORS

modpath fails if one or more of the following are true:

[EINVAL] The list of directories speciﬁed by pathname is malformed.

[ENOSYS] The Dynamically Loadable Kernel Module feature is not initialized.

[ENAMETOOLONG] pathname is more than

MAXPATHLEN characters long.

[EPERM] The calling process does not have appropriate privilege.
