opcodeinfo

Prints information on an opcode definition and its overloads.

Syntax

opcodeinfo(opc:OpcodeDef)
opcodeinfo(obj:Opcode)

opcodeinfo opc:OpcodeDef 
opcodeinfo obj:Opcode

Initialization

opc -- opcode definition

obj -- opcode object

This opcode prints information on the various overloads (versions) defined for an opcode, or alternatively the input and output arguments of an opcode object. It can be used to select the correct overload for instantiation with create.

Examples

Here is an example for opcodeinfo. It uses the file opcodeinfo.csd.

This should print

oscili: 10 overloads
(0) oscili.a    out-types: a    in-types: kkjo
(1) oscili.kk   out-types: k    in-types: kkjo
(2) oscili.ka   out-types: a    in-types: kajo
