CStruct

CStruct[name,members]

is a symbolic representation of a struct.

CStruct[name]

declares a struct without specifying the contents.

CStruct[None,members]

does not give the struct a name.

Details and Options

  • SymbolicC expressions are inert; they evaluate to themselves, staying in an unevaluated form.
  • SymbolicC expressions can be converted into a C string with ToCCodeString.
  • The members of the struct can be specified with lists or with CDeclare.

Examples

Basic Examples  (1)

To use SymbolicC, you first need to load the package:

Wolfram Language code: Needs["SymbolicC`"]

This creates a struct:

Wolfram Language code: CStruct["point", {{"double", "x"}, {"double", "y"}}]//ToCCodeString

You can use CDeclare to declare the members of the struct:

Wolfram Language code: CStruct["point", {CDeclare["double", "x"], CDeclare["double", "y"]}]//ToCCodeString

You can drop the name for the struct by using a specification of None:

Wolfram Language code: CDeclare[ CStruct[None, {{"double", "x"}, {"double", "y"}}], "pt1"]//ToCCodeString

You can drop the contents of the struct to make an incomplete type:

Wolfram Language code: CStruct["intlist", {{"int", "value"}, {CStruct["intlist"], CDereference["next"]}}]//ToCCodeString

You can use an incomplete type with a typedef:

Wolfram Language code: CTypedef[ CStruct["point"], CDereference["pt1"]]//ToCCodeString

You can nest a union inside a struct:

Wolfram Language code: CStruct["value", {{"int", "type"}, {CUnion[None, {{"int", "ival"}, {"double", "dval"}}], "data"}}]//ToCCodeString
