SetSecurityDescriptorGroup

The SetSecurityDescriptorGroup function sets the primary group information of an absolute-format security descriptor, replacing any primary group information already present in the security descriptor.

BOOL SetSecurityDescriptorGroup(

PSECURITY_DESCRIPTOR pSecurityDescriptor,	// address of security descriptor
PSID pGroup,	// address of SID for group
BOOL bGroupDefaulted	// flag for default
);

Parameters

pSecurityDescriptor

Points to the SECURITY_DESCRIPTOR structure whose primary group is set by this function. The function replaces any existing primary group with the new primary group.

pGroup

Points to a SID structure the function sets as the security descriptor's new primary group. The SID structure is referenced by, not copied into, the security descriptor. If this parameter is NULL, the function clears the security descriptor's primary group information. This marks the security descriptor as having no primary group.

bGroupDefaulted

Specifies a flag indicating whether the primary group information was derived from a default mechanism. If this flag is TRUE, it is default information, and the function stores this value as the SE_GROUP_DEFAULTED flag in the SECURITY_DESCRIPTOR_CONTROL structure. If this parameter is zero, the SE_GROUP_DEFAULTED flag is cleared.

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.
