I have a C program and I want to read data from a socket ,and especially I want a client to send a .jpg to the server.The problem I face is that no matter what the size of the photo is,my read command seems to read an amount of data and then does nothing.
The strange thing is that perror doesn't print anything,which means that read is successful,also I checked if I closed the socket in the server code,but I do not.
Hi
I have apeculiar problem with sockets.

For the first request, it is working fine i.e. client sends the req. and gets the... (1 Reply)

I need clarification on whether it is okay to set socket options on a listening socket
simultaneously when it is being used in an accept() call?
Following is the scenario:-
-- Task 1 - is executing in a loop - polling a listen socket, lets call it 'fd', (whose file descriptor is global)... (2 Replies)
Hello all,
I have a requirement to read and write to a tcp socket from an HP-UX shell script. I see a /dev/tcp character device on my servers:
crw-rw-rw- 1 root root 72 0x00004f Mar 28 18:37 /dev/tcp
So I believe this is what I should use. The problem is that all the... (2 Replies)

Hi,
When can the read() system call gives timeout error when the same connection worked for writing data to the other end of the socket, while the next call with read() gives timeout error?
Can anyone please explain when this kind of situation appears?
Thanks,

libssh2_sftp_read(3) libssh2 manual libssh2_sftp_read(3)NAME
libssh2_sftp_read - read data from an SFTP handle
SYNOPSIS
#include <libssh2.h> #include <libssh2_sftp.h>
ssize_t libssh2_sftp_read(LIBSSH2_SFTP_HANDLE *handle, char *buffer, size_t buffer_maxlen);
DESCRIPTION
handle is the SFTP File Handle as returned by libssh2_sftp_open_ex(3)
buffer is a pointer to a pre-allocated buffer of at least
buffer_maxlen bytes to read data into.
Reads a block of data from an LIBSSH2_SFTP_HANDLE. This method is modelled after the POSIX read(2) function and uses the same calling
semantics. libssh2_sftp_read(3) will attempt to read as much as possible however it may not fill all of buffer if the file pointer reaches
the end or if further reads would cause the socket to block.
RETURN VALUE
Number of bytes actually populated into buffer, or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block.
While LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
ERRORS
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_SOCKET_TIMEOUT -
LIBSSH2_ERROR_SFTP_PROTOCOL - An invalid SFTP protocol response was received on the socket, or an SFTP operation caused an errorcode to be
returned by the server.
