## Function Documentation

## snd_lib_error_set_local()

snd_local_error_handler_t snd_lib_error_set_local | ( | snd_local_error_handler_t | func | ) |

Install local error handler.

Parameters

  func | The local error handler function

Return values

  Previous | local error handler function

## snd_strlcpy()

size_t snd_strlcpy | ( | char * | dst,
|  | const char * | src,
|  | size_t | size
| ) |  |

Copy a C-string into a sized buffer.

Parameters

  dst | Where to copy the string to
  src | Where to copy the string from
  size | Size of destination buffer

Return values

  The | source string length

The result is always a valid NUL-terminated string that fits in the buffer (unless, of course, the buffer size is zero). It does not pad out the result like strncpy() does.

## Variable Documentation

## snd_err_msg

snd_lib_error_handler_t snd_err_msg = snd_err_msg_default
