C# order of bytes sent and received by socket -


i wondering order of sent , received bytes by/from tcp socket.

i got implemented socket, it's , working, that's good. have called "a message" - it's byte array contains string (serialized bytes) , 2 integers (converted bytes). has - project specifications :/

anyway, wondering how working on bytes: in byte array, have order of bytes - 0,1,2,... length-1. sit in memory.

how sent? last 1 first send? or first? receiving, think, quite easy - first byte appear gets on first free place in buffer.

i think little image made nicely shows mean.

sending on tcp

they sent in same order present in memory. doing otherwise more complex... how if had continuous stream of bytes? wait last 1 has been sent , reverse all? or inversion should work "packet packet"? each block of 2k bytes (or whatever size of tcp packets) internally reversed order of packets "correct"?

receiving, think, quite easy - first byte appear gets on first free place in buffer.

why on earth sender should reverse bytes receiver shouldn't? if build symmetric system, both action or none it!

note real problem 1 of endianness. memory layout of int on computer different layout of int of computer. 1 of 2 computers have reverse 4 bytes of int. endianness resolved "primitive type" "primitive type". many internet protocols, historical reason, big endian, while intel cpus little endians. internal fields of tcp big endian (see big endian or little endian on net?), here speaking of fields of tcp, not of data moved tcp protocol.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

php - Nothing but 'run(); ' when browsing to my local project, how do I fix this? -

i added new project. made mistake in projectname.conf file in sites-available apache2, led me reinstalling apache2. after reinstalling , re-enabling projects on every page of every project .. <body> run(); </body> .. i've run composer update, restarted service, restarted pc, checked config files, tried disabling new project. there nothing in error log, , access.log: 127.0.0.1 - - [15/may/2015:01:40:47 +0200] "get / http/1.1" 304 181 "-" "mozilla/5.0 (x11; ubuntu; linux x86_64; rv:38.0) gecko/20100101 firefox/38.0" maybe i'm forgetting apache2 reinstall? don't think did different last time installed it. looks haven't setup php correctly. take @ this great guide , maybe you're forgetting link php config apache2.
