The GetSecurityDescriptorLength function returns the length, in bytes, of a structurally valid security descriptor. The length includes the length of all associated structures.
Syntax
DWORD WINAPI GetSecurityDescriptorLength( _In_ PSECURITY_DESCRIPTOR pSecurityDescriptor );
Parameters
- pSecurityDescriptor [in]
-
A pointer to the SECURITY_DESCRIPTOR structure whose length the function returns. The pointer is assumed to be valid.
Return value
If the function succeeds, the function returns the length, in bytes, of the SECURITY_DESCRIPTOR structure.
If the SECURITY_DESCRIPTOR structure is not valid, the return value is undefined.
