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)
