In the below code I tried to read the entered text in a buffer and showing the length of data read from stdin.
Code:
#include <stdio.h>
#include <wchar.h>
#include <stdlib.h>
#include <locale.h>
#define BUFSIZE 256
wchar_t* readFromStdin(const wchar_t *);
wchar_t m_buf[BUFSIZE];
int main()
{
const wchar_t *pwch;
char *pbuf = NULL;
setlocale(LC_ALL, "");
printf("Enter the word having extended characters:");
pwch = readFromStdin(L"Word: ");
printf("The Wide char string is: %S\n", pwch);
wcstombs(pbuf, pwch, wcslen(pwch)+1); // I have to convert the wchar_t data to char* for further processing
return 0;
}
wchar_t *readFromStdin(const wchar_t *ptr) // Though this function is not doing what its name suggests
{
unsigned int size;
scanf("%ls",m_buf);
size = wcslen(m_buf);
printf("Size of buf = %d\n", size);
return (m_buf);
}
Whether this code will properly read any word having extended ascii characters and be able to show the desired length of the word.?
Thanks,

Please use CODE tags (not ICODE tags) for multi-line input, output, and code samples.

Hi All,
I'm trying to send extended ascii characters to my HP2055 as part of PCL printer control codes. What I want to do is select a bar code font, print the bar code and reset the printer to the default font.
Selecting the bar code font works good. Printing the bar code goes almost ok too. ... (5 Replies)

Is there a way to identify the lines in a file having extended ascii characters and display the same?
For instance I have a file abc.txt having below data

We are getting extended Ascii characters in the input file and my requirement is to search and replace them with a space. I am using the following command

libssh2_channel_handle_extended_data2(3) libssh2 manual libssh2_channel_handle_extended_data2(3)NAME
libssh2_channel_handle_extended_data2 - set extended data handling mode
SYNOPSIS
#include <libssh2.h>
int libssh2_channel_handle_extended_data2(LIBSSH2_CHANNEL *channel, int ignore_mode);
DESCRIPTION
channel - Active channel stream to change extended data handling on.
ignore_mode - One of the three LIBSSH2_CHANNEL_EXTENDED_DATA_* Constants.
LIBSSH2_CHANNEL_EXTENDED_DATA_NORMAL: Queue extended data for eventual reading
LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE: Treat extended data and ordinary data the same. Merge all substreams such that calls to libssh2_chan-
nel_read(3) will pull from all substreams on a first-in/first-out basis.
LIBSSH2_CHANNEL_EXTENDED_DATA_IGNORE: Discard all extended data as it arrives.
Change how a channel deals with extended data packets. By default all extended data is queued until read by libssh2_channel_read_ex(3)RETURN VALUE
Return 0 on success or LIBSSH2_ERROR_EAGAIN when it would otherwise block.
