NTSUCCESSStatus

NTSUCCESSStatus is a symbolic constant used in NT-based status reporting to indicate that an operation completed successfully. It is used in systems and libraries that implement Windows NT–style error handling and sits alongside a broader family of status codes that distinguish success from various error conditions. In many implementations, NTSUCCESSStatus corresponds to the canonical success value of zero, mirroring the well-known STATUS_SUCCESS used in Windows NT headers. However, because NTSUCCESSStatus is not a single standardized symbol across all projects, its exact numeric value and usage can vary by codebase.

Typical usage involves returning a status value from functions that perform operations such as I/O, resource management, or kernel interactions. Code may test for success by comparing the returned value to NTSUCCESSStatus or by using a helper macro such as NT_SUCCESS(status). In debugging or logging, NTSUCCESSStatus may be recorded as 0 or as a named constant to emphasize successful completion.

Relation to Windows semantics: In official Windows APIs, STATUS_SUCCESS (0x00000000) represents success, and a macro like NT_SUCCESS tests for a nonnegative or zero value depending on convention. NTSUCCESSStatus is conceptually aligned with that approach but is not part of the standard Windows header set; implementations differ. See also NTSTATUS and STATUS_SUCCESS for broader context on Windows NT–style status codes.
