SetAclInformation

The SetAclInformation function sets information about an access-control list (ACL).

BOOL SetAclInformation(
  PACL pAcl,               // address of access-control list
  LPVOID pAclInformation,  // address of ACL information
  DWORD nAclInformationLength,
                           // size of ACL information
  ACL_INFORMATION_CLASS dwAclInformationClass 
                           // specifies class of requested info
);
 

Parameters

pAcl

Points to an ACL structure. The function sets information in this ACL.

pAclInformation

Points to a buffer containing the information to be set. For the current version of Windows NT, this must be an ACL_REVISION_INFORMATION structure.

nAclInformationLength

Specifies the size, in bytes, of the buffer pointed to by the pAclInfo parameter.

dwAclInformationClass

Specifies an ACL_INFORMATION_CLASS enumerated type that gives the class of information requested.

Currently, this parameter can be AclRevisionInformation. This means that the buffer pointed to by the pAclInformation parameter contains an ACL_REVISION_INFORMATION structure.

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.
