程式範例: (我自己寫的)

> -----------------------------------------
#include "stdio.h"
#include "stdarg.h" //需要這個函式庫 ( va_list, va_start, va_arg, va_end )

void test_va_fun( int n, ... )
{
    char *string = NULL;

    va_list arg_ptr;
    va_start( arg_ptr, n );

    for( int i = 0; i < n; i++ )
    {
        string = va_arg( arg_ptr, char* );
        if(!string)
        {
            string = (char*)"";
        }

        printf("the %d string: %s\n", i+1, string);
    }

    va_end( arg_ptr );
    return;
}


int main( void )
{
    test_va_fun( 3, "TEST 1", "TEST 2", "TEST 3" );
    test_va_fun( 5, "1", "2", "3", "4", "5" );

    return 0;
}

> ---------------------------------------------------
輸出:

the 1 string: TEST 1
the 2 string: TEST 2
the 3 string: TEST 3
the 1 string: 1
the 2 string: 2
the 3 string: 3
the 4 string: 4
the 5 string: 5
