const char *mysql_error(MYSQL *mysql)
Description
For the connection specified by mysql,
mysql_error() returns a null-terminated
string containing the error message for the most recently
invoked API function that failed. If a function didn't fail,
the return value of mysql_error() may be
the previous error or an empty string to indicate no error.
A rule of thumb is that all functions that have to ask the
server for information reset mysql_error()
if they succeed.
For functions that reset mysql_errno(), the
following two tests are equivalent:
if(mysql_errno(&mysql))
{
// an error occurred
}
if(mysql_error(&mysql)[0] != '\0')
{
// an error occurred
}
The language of the client error messages may be changed by
recompiling the MySQL client library. Currently, you can
choose error messages in several different languages. See
Section 5.10.2, “Setting the Error Message Language”.
Return Values
A null-terminated character string that describes the error.
An empty string if no error occurred.
Errors
None.
