| snd_local_error_handler_t snd_lib_error_set_local | ( | snd_local_error_handler_t | func | ) |
Install local error handler.
| func | The local error handler function |
| Previous | local error handler function |
| size_t snd_strlcpy | ( | char * | dst, |
| const char * | src, | ||
| size_t | size | ||
| ) |
Copy a C-string into a sized buffer.
| dst | Where to copy the string to |
| src | Where to copy the string from |
| size | Size of destination buffer |
| 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.
| snd_lib_error_handler_t snd_err_msg = snd_err_msg_default |
