loadstruct

Purpose

Loads a structure into memory from a file on the disk.

Format

{ instance, retcode } = loadstruct(file_name, structure_type)

Parameters:

• file_name (string) – name of file containing structure.

• structure_type (string) – structure type.

Returns:

• instance (struct) – instance of the struct.

• retcode (scalar) – 0 if successful, otherwise 1.

Examples

Single Instance of Structure

#include ds.sdf
struct DS p3;

{ p3, retc } = loadstruct("p2", "ds");

Array of structures

First, define a new structure country, declare and instance countries, reshape it to an array, and save the structure to disk.

struct country
{
  string name;
  scalar population;
};

struct country countries;
countries = reshape(countries, 2, 1);

countries[1].name = "Canada";
countries[1].population = 37;
countries[2].name = "China";
countries[2].population = 1386;

retc = saveStruct(countries, "countries");

Now load the saved instance as a new instance countries_new

struct country countries_new;
countries_new = reshape(countries_new, 2, 1);

{ countries_new, retcode } = loadStruct("countries", "country");

Remarks

instance can be an array of structures.
