ERROR_INVALID_DATATYPE - 1804 (0x70C)

Technical Meaning

The ERROR_INVALID_DATATYPE error code indicates that a function or operation received an invalid data type as one of its parameters. This can occur in various contexts where the system expects a specific type of input but receives something else.

Error Details

This generic error is returned when a function encounters a parameter with an incorrect data type. The exact nature of the invalid data type and the context in which this error occurs will depend on the specific API or function that generated the error.

Usage Context

The ERROR_INVALID_DATATYPE can be encountered in any scenario where functions expect certain types of input, such as integers, pointers, structures, or other custom-defined types. The error is typically returned by system APIs and libraries to indicate a failure due to an inappropriate data type being passed to the function.

Developer Interpretation

When encountering ERROR_INVALID_DATATYPE, developers should review the documentation for the specific API or function that generated this error. Ensure that all parameters are of the correct type as specified in the function's declaration. Common causes include passing a pointer where an integer is expected, or vice versa, or using a custom-defined structure with incorrect fields.

Related Errors

• ERROR_INVALID_PARAMETER (128): A more general error indicating that one or more parameters are invalid.
• ERROR_TYPE_MISMATCH (0x734): Another generic error related to data type mismatches, but may be specific to certain contexts.

FAQ

Q: What does the ERROR_INVALID_DATATYPE mean?

A: It indicates that a function received an incorrect data type as one of its parameters. Ensure all inputs match the expected types specified in the API documentation.

Q: How can I prevent this error from occurring?

A: Verify that all function calls include parameters of the correct data type. Use tools like static analyzers to help catch such issues early in development.

Summary

The ERROR_INVALID_DATATYPE is a generic error code indicating an invalid data type was passed to a function. Developers should consult API documentation and ensure parameter types match expectations to avoid this error.
