Wide string command line arguments in C
In C, wide string command line arguments can be handled using the wmain
function and wide character arrays. Here's an example of how you can work with wide string command line arguments:
c#include <stdio.h>
#include <wchar.h>
int wmain(int argc, wchar_t *argv[])
{
int i;
// Loop through each argument
for (i = 0; i < argc; i++)
{
// Print the wide string argument
wprintf(L"Argument %d: %ls\n", i, argv[i]);
}
return 0;
}
In the above example, the wmain
function is the wide string equivalent of the main
function. It takes two parameters: argc
(argument count) and argv
(argument vector). The argc
parameter indicates the number of wide string arguments passed to the program, and argv
is an array of wide character strings containing those arguments.
To compile the program, you'll need a C compiler that supports wide characters. For example, using GCC, you can compile the program like this:
gcc -o myprogram myprogram.c -lws2_32
Note that the -lws2_32
flag is required on Windows systems to link against the wide character version of the C runtime library.
Once the program is compiled, you can run it with wide string command line arguments:
arduinomyprogram "Hello" "नमस्ते" "こんにちは"
The program will print each wide string argument along with its corresponding index.
Remember to use wide string functions (wprintf
, wscanf
, etc.) to work with wide strings instead of their regular character counterparts (printf
, scanf
, etc.).
