SetAclInformation info Overview Group

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.

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.
