helloworld

A simple dynamic library used to show an example of how to write a preset for JavaCPP.

In the helloworld branch of bytedeco/javacpp-presets there is the helloworld preset to use helloworld library with JavaCPP.

Example

#include <stdio.h>
#include <stdbool.h>
#include <stdlib.h>
#include <wchar.h>
#include <time.h>
#include <limits.h>
#include "../src/helloworld.h"

int main(int argc, char** argv) {

    printf("READ -------------------------------------------------\n");
    bool bool_value = getBool();
    printBool(bool_value);
    char byte_value = getByte();
    printByte(byte_value);
    wchar_t c = getChar();
    printChar(c);
    short int s = getShort();
    printShort(s);
    int i = getInt();
    printInt(i);
    long l = getLong();
    printLong(l);
    char* a = getUtf8String();
    printUtf8String(a);

    struct Person p = getPerson();
    printPerson(p);

    struct Person *pp = getPersonPtr();
    printPersonPtr(pp);

    PersonType pt = getPersonType();
    printPersonType(pt);

    PersonTypePtr ptp = getPersonTypePtr();
    printPersonTypePtr(ptp);

    printf("WRITE ------------------------------------------------\n");
    printBool(true);
    printBool(false);
    printByte(CHAR_MIN);
    printByte(CHAR_MAX);
    printChar(WCHAR_MIN);
    printChar(WCHAR_MAX);
    printShort(SHRT_MIN);
    printShort(SHRT_MAX);
    printInt(INT_MIN);
    printInt(INT_MAX);
    printLong(LONG_MIN);
    printLong(LONG_MAX);
    printUtf8String(u8"Hello UTF-8 z\u00df\u6c34\U0001F34C string!");
