GetSecurityDescriptorGroup

The GetSecurityDescriptorGroup function retrieves the primary group information from a security descriptor.

BOOL GetSecurityDescriptorGroup(

PSECURITY_DESCRIPTOR pSecurityDescriptor,	// address of security descriptor
PSID *pGroup,	// address of pointer to group security identifier (SID)
LPBOOL lpbGroupDefaulted	// address of flag for default
);

Parameters

pSecurityDescriptor

Points to a SECURITY_DESCRIPTOR structure whose primary group information the function retrieves.

pGroup

Points to a pointer to a SID structure identifying the primary group when the function returns. (A SID is a security identifier.) If the security descriptor does not contain a primary group, the function sets the pointer pointed to by pGroup to NULL and ignores the remaining output parameter, lpbGroupDefaulted. If the security descriptor contains a primary group, the function sets the pointer pointed to by pGroup to the address of the security descriptor's group SID structure and provides a valid value for the variable pointed to by lpbGroupDefaulted.

lpbGroupDefaulted

Points to a flag set to the value of the SE_GROUP_DEFAULTED flag in the SECURITY_DESCRIPTOR_CONTROL structure when the function returns. If the value stored in the variable pointed to by the pGroup parameter is NULL, no value is set.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
