defcstruct

Arguments: &rest body

This macro is obsolete and kept for backward compatibility only. Please use def-foreign-type.

This macro defines a C structure to Lisp by defining appropriate accessor and creator functions. The creator function is named make-name. The accessor function names for each slot are the hyphen-separated concatenation of the cstruct name and the slot name.

Argument name is either the name of this cstruct or a list. In the latter case the first element of the list is the name of the cstruct and the second element may be the keyword :malloc.

Each slot is a list. The first item on the list is a symbol naming the slot, and the rest of the list specifies the datatype. A datatype takes one of the following forms:

:char
:byte
:short
:long
:unsigned-byte
:unsigned-short
:unsigned-long
:short-float
:long-float

This will provide space for the specified atomic C data type to be placed in that slot.
