TSdlProcessIO
Description of where standard I/O should be directed when creating a process.
If a standard I/O stream is set to Inherited, it will go to the same place as the application's I/O stream. This is the default for standard output and standard error.
If a standard I/O stream is set to Null, it is connected to NUL: on Windows and /dev/null on POSIX systems. This is the default for standard input.
If a standard I/O stream is set to App, it is connected to a new TSdlIOStream that is available to the application. Standard input will be available as TSdlProperty.ProcessStdIn and allows TSdlProcess.Input, standard output will be available as TSdlProperty.ProcessStdOut and allows TSdlProcess.Read and TSdlProcess.Output, and standard error will be available as TSdlProperty.ProcessStdErr in the properties for the created process.
If a standard I/O stream is set to Redirect, it is connected to an existing TSdlIOStream provided by the application. Standard input is provided using TSdlProperty.ProcessCreateStdIn, standard output is provided using TSdlProperty.ProcessCreateStdOut, and standard error is provided using TSdlProperty.ProcessCreateStdErr in the creation properties. These existing streams should be closed by the application once the new process is created.
In order to use an TSdlIOStream with Redirect, it must have TSdlProperty.IOStreamWindowHandle or TSdlProperty.IOStreamFileDescriptor set. This is True for streams representing files and process I/O.
