The GENERIC_MAPPING structure describes the ACCESS_MASK value of specific access rights associated with each type of generic access right.

typedef struct _GENERIC_MAPPING {
    ACCESS_MASK  GenericRead;
    ACCESS_MASK  GenericWrite;
    ACCESS_MASK  GenericExecute;
    ACCESS_MASK  GenericAll;
} GENERIC_MAPPING, *PGENERIC_MAPPING;

Members

GenericRead

Describes the specific access rights corresponding to the GENERIC_READ access right.

GenericWrite

Describes the specific access rights corresponding to the GENERIC_WRITE access right.

GenericExecute

Describes the specific access rights corresponding to the GENERIC_EXECUTE access right.

GenericAll

Describes the specific access rights corresponding to the GENERIC_ALL access right.

Comments

Use the IoGetFileObjectGenericMapping routine to get the specific access rights corresponding to generic access rights for file objects. Use RtlMapGenericMask to subtract off the access rights within an ACCESS_MASK that do not derive from generic access rights.

For more information about generic access rights, see the reference page for GENERIC_MAPPING in the Microsoft Windows SDK documentation.

Requirements
