I am able to connect But Unable to receive a File
Using the same code as example/scp.c (tried even the scp_nonblock.c)
Trace taken from the working example/scp.c
Read B lines come from my trace additions to transport.c
_libssh2_transport_read Function
Read B 2 just before if (session->state & LIBSSH2_STATE_NEWKEYS) {
Read B 3 just after remainbuf = p->writeidx - p->readied; prints writeidx
and readidx values
Read B 3 just before if (remainbuf < blocksize) { prints
remainbuf and blocksize values
Read B 3 A inside if (remainbuf < blocksize) { prints
remainbuf value
Read B 3 B just before nread = LIBSSH2_RECV(session, &p->buf[remainbuf],
PACKETBUFSIZE - remainbuf, ...
Read B 3 C right after the nread = LIBSSH2_RECV(session,
===== …. ==== sections appear during scp.c execution which works
but NOT during my execution
Code STOPS in the LIBSSH2_RECV function
Any Help Please ! !
Thanks in advance
