How to store the data in buffer

[jhamb]

Hello,

I want to read a file and to pass the values in a buffer but the values are of different datatype. So I cant put the values in the char type buffer.
What to do?

I found this but dint worked for me...

void print ( char *Buffer, usigned long bufferSize, int chunkSize );
 
/*This fn will accept file buffer and the buffer size and the chunk size
Send the buffer in chunks which is provided by the parameter.
*/
 
FILE *fp23 = fopen( "c:\\file.txt", "rb" );
 
fseek (fp23 , 0 , SEEK_END);
int m_jobSize = ftell (fp23);
rewind (fp23);
 
char* m_buffer = new char[m_jobSize+1];
int m_result = fread( m_buffer, 1, m_jobSize, fp23 );
int chunkSize = 1;
void print ( m_buffer, m_jobSize, chunkSize);
 
 
void print ( char *m_buffer, usigned long m_jobSize, int chunkSize)
{
    int BytesIndex = 0;
    while( bufsize > 0) 
    {
          if ( bufsize < (unsigned long)iSendStatus ) // Send some bytes
          {
              iSendStatus = send(*sock, &m_buffer[BytesIndex], bufsize, 0); 
                                                          // Call Back Function
              set += iSendStatus;
              ptr(jobid,set);
              if ( iSendStatus != bufsize )
              {
                   cpError = SocketErrorHandler();
                   return cpError;
              }
 
         }
         else
         {
             iSendStatus = send(*sock, &m_buffer[BytesIndex], chunkSize, 0); 
                                                         // Call Back Function
             set += iSendStatus;
             ptr(jobid,set);
 
             if ( iSendStatus != chunkSize )
             {
                 cpError = SocketErrorHandler();
                 return cpError;
             }
 
        } 
                                               // Update buffer and counter
       if ( bufsize < (unsigned long)iSendStatus )
       {
          bufsize -= bufsize;
          BytesIndex += bufsize;
       }
      else
      { 
         bufsize -= iSendStatus;
         BytesIndex +=iSendStatus;
      }
}
 

Anyone can help..!
Thanks :)

fread() doesn't care what the buffer type is. That argument is a void*. Just define your buffer of the correct type and pass the address to fread().

Couldn't make out with the work, still.
Dint understood, how to do..!

This is fread() prototype:

size_t fread( 
   void *buffer,
   size_t size,
   size_t count,
   FILE *stream 
);
 

To read 1000 ints you would:

int buffer[1000]
fread(buffer, sizeof(int), 1000, myFile);
