I am not sure why you want to do this. On which task are you currently
working?
I am working on the 2nd task to modify the record-client program to read
from a file if a --input=<FILE> command line option is given.
Could you please check in the part which adds the new option and the
code which opens the file.
client_item record;
while(fread(&record, sizeof(record), 1, input_file))
printf ("CPU=%d\n",record.cpu);
Here input_file is a file provided through the command.
The TCP stream you saved with nc from the target consists of struct
rtems_record_item_32. In the code above you read struct client_item
items. This cannot be right. When you don't know which content a file
has, please ask.
You have to change this code here:
while ( true ) {
int buf[ 8192 ];
ssize_t n;
n = recv( fd, buf, sizeof( buf ), 0 );
if ( n >= 0 ) {
rtems_record_client_run( &ctx, buf, (size_t) n );
} else {
break;
}
}
First you should refactor the code and move the TCP relates stuff into
separate functions.
