/sockread [-fn] [numbytes] <%var|&binvar>
The /sockread command reads bytes from the receive buffer into the specified variable.
If you specify a %var variable, a line of text ending with a Carriage Return/LineFeed is read into %var. The $crlf are stripped off (this may result in %var being $null if the line only consisted of $crlf).
If you specify the -f switch with a %var variable, this forces mIRC to fill the %var variable with whatever text is in the receive buffer, even if it doesn't end in a $crlf.
If you specify a &binvar then [numbytes] of info is read into the binary variable. If no [numbytes] is specified it defaults to 4096 bytes. The &binvar is unset before filling it with the read data.
The -n switch allows you to read a $crlf terminated line into a &binvar. If the incoming line does not contain a $crlf, no bytes will be read into &binvar, unless you specify the -f switch, which forces the read (same as when reading into %vars).
Note: A single /sockread may not be enough to read the entire buffer. You should keep reading until $sockbr (bytes read) is set to zero. This is far faster than letting mIRC re-trigger the event. If your script doesn't read the whole buffer, the on sockread event is re-triggered if: a) you were reading into a &binvar. b) you were reading into a %var and there is still a $crlf terminated line in the buffer waiting to be read.
Example: This example shows you how you should process a sockread event. The socket has already been opened and has received information, so the sockread event is triggered. The socket name is testing.
on 1:sockread:testing:{
;when a sockerror occured, return
if ($sockerr > 0) return
;start the loop to be able to sockread multiple times
while (1) {
sockread %temp
;when nothing is read, the buffer was empty, so we return
if ($sockbr == 0) return
echo -ag sockread: %temp
}
}
