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
funcThe local error handler function
Return values
Previouslocal 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
dstWhere to copy the string to
srcWhere to copy the string from
sizeSize of destination buffer
Return values
Thesource 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.
