SetSecurityDescriptorGroup function

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.

Syntax


BOOL WINAPI SetSecurityDescriptorGroup(
  _Inout_   PSECURITY_DESCRIPTOR pSecurityDescriptor,
  _In_opt_  PSID pGroup,
  _In_      BOOL bGroupDefaulted
);

Parameters

pSecurityDescriptor [in, out]

A pointer 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 [in, optional]

A pointer to a SID structure for 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 [in]

Indicates whether the primary group information was derived from a default mechanism. If this value 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 value

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.
