2.2.2.1 _DEVMODE

The _DEVMODE structure defines initialization data for a printer. Although the _DEVMODE structure does not contain any pointers, it is still custom-marshaled, because the size of the structure is version-specific and implementation-specific, and cannot be expressed using IDL attributes. It has the following message format.

The print server MUST accept _DEVMODE structures with truncated public information. A truncated _DEVMODE structure contains a subset of fields, from dmDeviceName up to and including dmFields, plus at least those fields that are initialized as specified by dmFields. It is followed by private, printer driver–specific data, the size of which is specified by the dmDriverExtra field.

dmDriverExtraData (variable)

...

dmDeviceName (64 bytes): A 32-element array of 16-bit Unicode characters that form a null-terminated string that specifies the name of the printer. Printer name strings that are longer than 32 characters are truncated to fit the array. For more rules governing printer names, see section 2.2.4.14.

dmSpecVersion (2 bytes): The version of initialization data specification on which the _DEVMODE structure is based. This value SHOULD be 0x0401.<104>

dmDriverVersion (2 bytes): For printers, an optional, implementation-defined version of the printer driver.<105>

dmSize (2 bytes): The size, in bytes, of the _DEVMODE structure, which MUST be a multiple of 4. This value does not include the length of any private, printer driver–specific data that follows the _DEVMODE structure's public fields. The size of private data is specified by the dmDriverExtra value.

If the _DEVMODE structure contains truncated public information, the value of dmSize is at least the size, in bytes, of a subset of fields, from dmDeviceName up to and including dmFields, plus fields that are initialized as specified by dmFields.

dmDriverExtra (2 bytes): The size, in bytes, of the private, printer driver–specific data that follows this structure.

dmFields (4 bytes): A bitfield that specifies the fields of the _DEVMODE structure that have been initialized. If a bit is set, the corresponding field MUST be initialized and MUST be processed on receipt. If a bit is not set, the value of the corresponding field SHOULD be zero when sent and MUST be ignored on receipt.

The value of this field is the result of a bitwise OR of the following bits.
