@doc EXTERNAL IFAXOS DATATYPES
@types BUFFER | The Buffer structure defines the buffer header structures which processes manipulate.
@field WORD | fReadOnly | Specifies whether the buffer is readonly or not. It is the applications responsibility to check this flag and not violate it. <f IFBufMakeWritable> should be used if a process needs to write on a buffer which is marked readonly. This field should not be modified by the process itself.
@field LPBYTE | lpbBegBuf | A far ptr pointing to the physical start of the buffer. This ptr has meaning only in the calling process's address space and should not be stored for any reason. It should not be modified either.
@field WORD | wLengthBuf | Physical length of the buffer. Should not be modified by the process. Should be used in conjunction with <e BUFFER.lpbBegBuf> to know the physical boundaries of the buffer.
@field DWORD | dwMetaData | Indicates the kind of data stored in the buffer. See <t STD_DATA_TYPES> for all the possible values of this field.
@field LPBYTE | lpbBegData | Far ptr to the start of valid data in the buffer. The process is responsible for maintaining the integrity of this as it consumes or produces data in the buffer. The ptr should not be passed to any other process as it will not be valid. At buffer allocation time this field is initialized to point to the physical beginning of the buffer.
@field LPBYTE | lpbCurPtr | One of the fields of a union containing lpbfNext and dwTemp as its other members. A general purpose far ptr which can be used to mark an interesting place in the buffer. Should be used as a temporary variable while processing the buffer. Should not be directly passed to any other process. Initialized to point to the beginning of the buffer at allocation time. Remember that this is a UNION !!
@field LPBUFFER | lpbfNext | One of the fields of a union containing lpbCurPtr and dwTemp as its other members. This should be used when a module wants to internally link a list of buffers together. Remember that this is a UNION !!
@field DWORD | dwTemp | One of the fields of a union containing lpbfNext and lpbCurPtr as its other members. This should be used when the module wants to store some random information in the header. Remember that this is a UNION !!
@field WORD | wLengthData | Gives the length of valid contiguous data present in the buffer starting at <e BUFFER.lpbBegData>. The process is responsible for maintaining the integrity of this. Initialized to zero at allocation time.
@comm There are other reserved fields in the structure which have not been mentioned here.

@type DWORD | STD_DATA_TYPES | Standard data types used for specifying the format of data in the system.
@emem MH_DATA | Modified Huffman (T.4 1-dimensional). @emem MR_DATA | Modified READ (T.4 2-dimensional). @emem MMR_DATA| Modified Modified READ (T.6). @emem LRAW_DATA | Raw bitmap data, Least Significant Bit to the left. @emem HRAW_DATA | Raw Bitmap data, Most Significant Bit to the left. @emem DCX_DATA | Industry standard DCX specification (collection of PCX pages). @emem ENCRYPTED_DATA | Data encrypted - original format unspecified. @emem SIGNED_DATA | Data along with a digital signature. @emem BINFILE_DATA | Arbitrary binary data. @emem STORED_BUF_DATA | Contains a BUFFER header & data. @emem DCP_TEMPLATE_DATA | Digital Cover Page template data. @emem DCP_DATA | Digital Cover Page processed template data. @emem SPOOL_DATA | Spool data type - same as MMR for now. @emem PRINTMODE_DATA | Printer Mode structure. @emem ASCII_DATA | Ascii text. @emem OLE_DATA | Ole object. @emem OLE_PICTURE | Ole Rendering Data. @emem END_OF_PAGE | End of page marker. @emem END_OF_JOB | End of job marker. @emem CUSTOM_METADATA_TYPE | Beyond this value custom data types can be defined.
@comm This should be used to specify data type of any data stream in the system - from BUFFERS to Linearized Messages. All data types which need to be used in bit fields (i.e. the Format Resolution) must have a value which is a power of 2. Other data types which do not need to used in a bit field context may be assigned the other values.********/
