## Typedefs

typedef void(* | snd_lib_log_handler_t) (int prio, int interface, const char *file, int line, const char *function, int errcode, const char *fmt, va_list arg)
| Log handler callback.
typedef void(* | snd_lib_error_handler_t) (const char *file, int line, const char *function, int errcode, const char *fmt,...)
| Error handler callback.
typedef void(* | snd_local_error_handler_t) (const char *file, int line, const char *func, int errcode, const char *fmt, va_list arg)

## Functions

const char * | snd_strerror (int errnum)
| Returns the message for an error code.
int | snd_lib_log_filter (int prio, int interface, const char *configstr)
| Check if a log message should be shown based on LIBASOUND_DEBUG.
void | snd_lib_log (int prio, int interface, const char *file, int line, const char *function, int errcode, const char *fmt,...)
| Root log handler function.
void | snd_lib_check (int interface, const char *file, int line, const char *function, int errcode, const char *fmt,...)
| The check point function.
snd_lib_log_handler_t | snd_lib_log_set_handler (snd_lib_log_handler_t handler)
| Sets the log handler.
snd_lib_log_handler_t | snd_lib_log_set_local (snd_lib_log_handler_t handler)
| Install local log handler.
const char * | snd_lib_log_priority (int prio)
| Function to convert log priority level to text.
const char * | snd_lib_log_interface (int interface)
| Function to convert interface code to text.
int | snd_lib_error_set_handler (snd_lib_error_handler_t handler)
| Sets the error handler.
snd_local_error_handler_t | snd_lib_error_set_local (snd_local_error_handler_t func)
| Install local error handler.
