[OS_Process->ReadString] reads any available data from the standard output of the native process and returns a string value. This tag accepts two parameters. The first specifies the maximum number of bytes of data to retrieve. The tag will return all available data up to that number of bytes. By default all available data will be retrieved. A
If [OS_Process->SetEncoding] has been called then the data from the native process is automatically translated from the specified character set to Lasso's native string format. If no encoding has been specified then Lasso expects the process to return data in UTF-8 format.
Var: 'myProcess' = (OS_Process: '/bin/cat');
$myProcess->(SetEncoding: 'iso-8859-1');
$myProcess->(Write: 'This is a test\n');
$myProcess->CloseWrite;
encode_html: $myProcess->ReadString;
$myProcess->Close;
