GetAclInformation

The GetAclInformation function retrieves information about an access-control list (ACL).

BOOL GetAclInformation(

PACL pAcl,	// pointer to access-control list
LPVOID pAclInformation,	// pointer to ACL information
DWORD nAclInformationLength,	// size of ACL information
ACL_INFORMATION_CLASS dwAclInformationClass	// class of requested information
);

Parameters

pAcl

Points to an ACL structure. The function retrieves information about this ACL.

pAclInformation

Points to a buffer receiving the requested information. The structure put into the buffer depends on the information class requested in the dwAclInformationClass parameter.

nAclInformationLength

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

dwAclInformationClass

Specifies an ACL_INFORMATION_CLASS enumerated type that gives the class of information requested. This parameter can be one of two values from this enumerated type. If the value is AclRevisionInformation, the function fills the buffer pointed to by the pAclInformation parameter with an ACL_REVISION_INFORMATION structure.

If the value is AclSizeInformation, the function fills the buffer pointed to by the pAclInformation parameter with an ACL_SIZE_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.
