Description
mysql_real_connect_nonblocking()
is an asynchronous function. It is the counterpart of the
mysql_real_connect()
synchronous function, for use by applications that require
asynchronous communication with the server. For general
information about writing asynchronous C API applications,
see Section 28.7.12, “C API Asynchronous Interface”.
mysql_real_connect_nonblocking()
is used similarly to
mysql_real_connect(). For
details about the latter, see
Section 28.7.7.54, “mysql_real_connect()”. The two functions differ
as follows:
mysql_real_connect()returns a connection handler orNULL.mysql_real_connect_nonblocking()returns anenum net_async_statusstatus indicator.
mysql_real_connect_nonblocking()
was added in MySQL 8.0.16.
Returns an enum net_async_status value. See
the description in
Section 28.7.13, “C API Asynchronous Interface Data Structures”. A
NET_ASYNC_ERROR return status indicates an
error.
