GetSystemVersion

The GetSystemVersion method returns information that identifies the operating system on the computer that is running the current target.

HRESULT
  IDebugControl::GetSystemVersion(
    OUT PULONG  PlatformId,
    OUT PULONG  Major,
    OUT PULONG  Minor,
    OUT OPTIONAL PSTR  ServicePackString,
    IN ULONG  ServicePackStringSize,
    OUT OPTIONAL PULONG  ServicePackStringUsed,
    OUT PULONG  ServicePackNumber,
    OUT OPTIONAL PSTR  BuildString,
    IN ULONG  BuildStringSize,
    OUT OPTIONAL PULONG  BuildStringUsed
    );

Parameters

PlatformId

Receives the platform ID. PlatformId is always VER_PLATFORM_WIN32_NT for NT-based Windows.

Major

Receives 0xF if the target's operating system is a free build, or 0xC if the operating system is a checked build.

Minor

Receives the build number for the target's operating system.

ServicePackString

Receives the string for the service pack level of the target computer. If ServicePackString is NULL, this information is not returned. If no service pack is installed, ServicePackString can be empty.

ServicePackStringSize

Specifies the size, in characters, of the buffer that ServicePackString specifies.

ServicePackStringUsed

Receives the size, in characters, of the string of the service pack level. If ServicePackStringUsed is NULL, this information is not returned.

ServicePackNumber

Receives the service pack level of the target's operating system.

BuildString

Receives the string that identifies the build of the system. If BuildString is NULL, this information is not returned.

BuildStringSize

Specifies the size, in characters, of the buffer that BuildString specifies.

BuildStringUsed

Receives the size, in characters, of the string that identifies the build. If BuildStringUsed is NULL, this information is not returned.

Return Value

S_OK

The method was successful.

S_FALSE

The method was successful. However, the ServicePackString buffer or the BuildString buffer were too small and the corresponding string was truncated.

This method may also return error values. See Return Values for more details.
