mysql_connect()
MYSQL *mysql_connect(MYSQL *mysql, const char *host, const char *user, const char *passwd)
This function is deprecated. It is preferable to use
mysql_real_connect()
instead.
mysql_connect()
attempts to establish a connection to a MySQL
database engine running on host
. mysql_connect()
must complete
successfully before you can execute any of the other API functions, with the
exception of mysql_get_client_info()
.
The meanings of the parameters are the same as for the corresponding
parameters for mysql_real_connect()
with the difference that the
connection parameter may be NULL
. In this case the C API
allocates memory for the connection structure automatically and frees it
when you call mysql_close()
. The disadvantage of this approach is
that you can't retrieve an error message if the connection fails. (To
get error information from mysql_errno()
or mysql_error()
,
you must provide a valid MYSQL
pointer.)
