PREfast Warning 241 (Windows CE 5.0)

Send Feedback

241 - Value returned from the finally-block overrides the value returned from its corresponding try-block.
Additional Information: See previous return at <location>.

This warning indicates that return statements occur in both the protected and handler blocks of a try/finally statement.

When a value is returned from both the protected and handler blocks of a try/finally statement, the last value returned (the one from the finally block) wins.

Example

__try {
    if (rand()) {
        return 1;

}

__try {
    if (rand()) {
        RetVal = 1;
        __leave;
    }
} __finally {
    if (rand()) {
        RetVal = 2;
