Explore libstruct Objects

This example shows how to display information about and modify a libstruct object,c_struct.

Load theshrlibsamplelibrary containing thec_structdefinition.

ifnot(libisloaded('shrlibsample')) addpath(fullfile(matlabroot,'extern','examples','shrlib')) loadlibrary('shrlibsample')end

Create thelibstructobject. Objectscis an instance of a MATLAB class calledlib.c_struct.

sc = libstruct('c_struct')

sc = lib.c_struct

Set structure field values.

set(sc,'p1', 100,'p2',150,'p3',200)

Display field values.

get(sc)

p1: 100 p2: 150 p3: 200

Modify values using MATLAB field structure syntax.

sc.p1 = 23; get(sc)

p1: 23 p2: 150 p3: 200
