## Macro Definition Documentation

## MAX_PLUGINS

#define MAX_PLUGINS 256

Max number if plugins handled.

No point to malloc() this.

Definition at line 40 of file drv_admin.c.

## Function Documentation

## for_each_driver()

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.

## for_each_plugin()

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.

## hw_choose_driver()

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.

## hw_print_drivers()

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.

Definition at line 270 of file drv_admin.c.

## Variable Documentation

## drv

struct driver drv

extern

Access to otherwise private drv.

Access to otherwise private drv.

Set by hw_choose_driver().
