Problem with ssh_scp_write() function

[Thomas Mayer]

Hi,
I wrote a little test program to copy a file from local to remote host. 
But I think there is some problem with the ssh_scp_write() function.
When I run my program (source code below) without the mssleep() 
function, only a very small file is created and the the programm exit 
without a error. With the mssleep() function all things work correctly 
and the file is copied complete.

Any idea what I'm doing wrong?


/// Test program
First I do the basic stuff like authentication, init new scp session, 
open local file to read and get local file size, etc...
Then I do (reduced source code):

ssh_scp_push_directoryssh_scp_push_directory(scp, ".", S_IRWXU);
ssh_scp_push_file(scp, "testFile.zip", localSize, S_IRUSR | S_IWUSR);

while (remoteSize != localSize)
    {
        count = fread(buffer, 1, sizeof(buffer), localFile);

        if (ssh_scp_write(scp, buffer, count) != SSH_OK)
        {
            qDebug() << "[ERROR] SshConnect::writeScpData: write error";
            fclose(lFile);
            return -1;
        }

        msleep(20);   // it don't works correct without that
        remoteSize += count;
    }



Thanks in advance,
Thomas
