Marshalling interface between provider and server

A computerized method of forming a request message buffer comprising the steps of:

• representing each of a plurality of data chunks to be stored in said request message buffer by a respective chunk object;
• declaring each of said chunk objects as a variable on a stack;
• storing a first of said data chunks in a first area of said request message buffer;
• storing a second of said data chunks in a second area of said request message buffer;
• and
• employing the chunk object representing said first data chunk to locate said first data chunk in the course of loading data representing the location of said second data chunk into said first data chunk, wherein the data representing the location of said second chunk comprises an offset from a base address, and each said chunk object further contains a pointer to a request object.

An article of manufacture comprising:

• a computer usable medium having computer readable program code means embodied in said medium, the computer readable code means comprising:
• means for defining a request message buffer comprising a series of data structures, each of said data structures including a length field and a plurality chunks, a first of said chunks including a reference to the location in the request message buffer of a second of said chunks, said reference comprising an offset value which represents a quantity by which the beginning of said second chunk is offset from the base address of the request message buffer;
• and
• means for representing each respective chunk of the request message buffer by an object variable, each object variable comprising two pieces of information:
• the offset value of the respective chunk and a pointer to a request object.

Computer executable process steps operative to control a computer and stored on a computer readable medium, said steps being operative to:

• define a request message buffer comprising a series of data structures, said data structures including a length field and a plurality chunks, a first of each of said chunks including a reference to the location in the request message buffer of a second of said chunks, said reference comprising an offset value which represents a quantity by which the beginning of said second chunk is offset from the base address of the request message buffer;
• and
• represent each respective chunk of the request message buffer by an object variable, each object variable comprising two pieces of information:
• the offset value of the respective chunk and a pointer to a request object.
