n is a signed int, there isn't an issue there. &nbsp;ioctlsocket is a windows function, not a linux function. &nbsp;I've looked for a reference to ioctl() to find the parameters to get how much data is in the socket waiting to be read, but I haven't found it yet. &nbsp;Could you point me to a reference?

I found the solution thanks to you. &nbsp;I can use &nbsp;ioctl(file_descriptor, FIONREAD, &amp;byte_count_variable) to see how much data is waiting to be read and loop off of that. &nbsp;Works great. &nbsp;Thanks.

<div class="content wysiwyg-content">
Lang: C/C++<br />
OS: Ubuntu<br />
Compiler: g++<br />
Interface to server: Firefox web browser<br />
Problem: Loop Deadlocks<br />
<br />
while ( ( n = recv(slave_socket, buffer_pointer, 255, 0) ) &gt;&nbsp;0) {<br />
...prints to server terminal for time being...<br />
}<br />
<br />
buffer is 256, request is accepted, loop and browser deadlock<br />
Browser continuely waits for a response, server continuely waits for packets.<br />
<br />
Temporary Fix: buffer is 2048, replaced loop with if statement<br />
<br />
if ( ( n = recv(slave_socket, buffer_pointer, 2047, 0) ) &gt;&nbsp;0 ) { ... }<br />
<br />
Question: I would like to keep using the loop and fix the deadlocking, or atleast find another way so that the buffer can be dynamic so to accomidate any request and also to not waste space.

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
