The C implementation of the Wayland protocol abstracts the details of
logging. Users may customize the logging behavior, with a function conforming
to the wl_log_func_t type, via wl_log_set_handler_client and
wl_log_set_handler_server.
A wl_log_func_t must conform to the expectations of vprintf, and
expects two arguments: a string to write and a corresponding variable
argument list. While the string to write may contain format specifiers and
use values in the variable argument list, the behavior of any wl_log_func_t
depends on the implementation.
\note Take care to not confuse this with wl_protocol_logger_func_t, which
is a specific server-side logger for requests and events.
\param "const char *" String to write to the log, containing optional format
specifiers
\param "va_list" Variable argument list
