### 说明

The maxdb_connect_errno() function will return the last error code number for last call to maxdb_connect(). If no errors have occurred, this function will return zero.

### 返回值

An error code value for the last call to maxdb_connect(), if it failed. zero means no error occurred.

### 范例

Example #1 maxdb_connect_errno sample

    <?php
    $link = maxdb_connect("localhost", "XXXXXXXX", "YYYYYYYYY");

    if (!$link) {
       printf("Can't connect to localhost. Errorcode: %d\n", maxdb_connect_errno());
    }
