/sockread buffer overflow - 01/09/14 07:19 PM
Although one should always check there are data available before /sockreading, if you /sockread after emptying the receive buffer, mIRC will report there is data to be read, type /testsw :
Code:
alias testsw { sockclose testsw socklisten testsw 8005 .timer 1 1 sockopen testsw2 127.0.0.1 8005 } ;sending two bytes, $crlf on *:sockopen:testsw2:if (!$sockerr) sockwrite -n testsw2 on *:socklisten:testsw:if (!$sockerr) sockaccept testsw1 on *:sockread:testsw1:{ if (!$sockerr) { var %a echo -a $sock($sockname).rq sockread -f %a echo -a $qt(%a) -- $ascii(%a) sockread -f %a echo -a $qt(%a) -- $ascii(%a) sockclose testsw* } alias -l ascii returnex $regsubex($1-,/(*UTF8)(.)/g,$asc(\1) $+ $chr(32))
