Detailed Description

Routines for dynamic drivers.

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

Date
August 2014 GPL2 or later Drivers are loaded from a path defined by (falling priority):
  • The "lircd:pluginpath" option.
  • The LIRC_PLUGIN_PATH environment variable.
  • The hardcoded PLUGINDIR constant.

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 
)

Apply func to all existing drivers. Returns pointer to a driver if such a pointer is returned by func(), else NULL.

Definition at line 213 of file drv_admin.c.

void for_each_plugin ( plugin_guest_func  plugin_guest,
void *  arg 
)

Apply func to all plugins (i. e., .so-files) in current plugin path.

Definition at line 219 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 247 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
fileFile to print to.
