Functions in this file provides primitives to iterate over the dynamic drivers + a single function to install such a driver.

Drivers are loaded from a path defined by (falling priority):

• The "lircd:pluginpath" option.
• The LIRC_PLUGIN_PATH environment variable.
• The hardcoded PLUGINDIR constant.

Definition in file drv_admin.h.

Typedef Documentation

typedef struct driver*(* drv_guest_func) (struct driver *, void *)

Argument to for_each_driver().

Called with the loaded struct driver* data and the argument given to for_each_driver(). Returns NULL if iteration should continue, else a struct hardware* pointer.

Definition at line 32 of file drv_admin.h.

typedef struct driver*(* plugin_guest_func) (const char *, drv_guest_func, void *)

Argument to for_each_plugin.

Called with a path to the so-file, a function to apply to each found driver (see drv_guest_func()) and an untyped argument given to for_each_plugin(). Returns NULL if iteration should continue, else a struct driver* pointer.

Definition at line 41 of file drv_admin.h.

Function Documentation

struct driver* for_each_driver	(	drv_guest_func	func,
		void *	arg,
		const char *	pluginpath
	)

Apply func to all existing drivers.

Returns pointer to a driver if such a pointer is returned by func(), else NULL. Pluginpath defaults to lircd:pluginpath, LIRC_PLUGINPATH and a hardcoded last resort.

Definition at line 227 of file drv_admin.c.

void for_each_plugin	(	plugin_guest_func	plugin_guest,
		void *	arg,
		const char *	pluginpath
	)

Apply func to all plugins (i.

e., .so-files) in plugin path. plugin path default to lircd:pluginpath, LIRC_PLUGINPATH and a hardcoded last resort.

Definition at line 235 of file drv_admin.c.

int hw_choose_driver

(

const char *

name

)

Search for driver with given name, update global drv with driver data if found.

Returns

Returns 0 if found and hw updated, else -1.

Definition at line 297 of file drv_admin.c.

void hw_print_drivers

(

FILE *

file

)

Prints all drivers known to the system to the file given as argument.

Parameters

file	File to print to.
