Declaration

Source position: amigados.pas line 2244

function CliInitNewcli(

  dp: PDOSPacket

):LongInt;

Arguments

dp

  

startup arguments that were passed to the shell If NULL, defaults will be used

Function result

Flags or a Pointer

Description

This function initializes a process and CLI structure for a new shell, from parameters in an initial packet passed by the system (NewShell or NewCLI, etc). The format of the data in the packet is purposely not defined. The setup includes all the normal fields in the structures that are required for proper operation (current directory, paths, input streams, etc).

It returns a set of flags containing information about what type of shell invocation this is.

Definitions for the values of fn:

Bit 31
Set to indicate flags are valid
Bit 3
Set to indicate asynch system call
Bit 2
Set if this is a SystemTagList() call
Bit 1
Set if user provided input stream
Bit 0
Set if RUN provided output stream

If Bit 31 is 0, then you must check IoErr() to determine if an error occurred. If IoErr() returns a pointer to your process, there has been an error, and you should clean up and exit. The packet will have already been returned by CliInitNewcli(). If it isn't a pointer to your process and Bit 31 is 0, reply the packet immediately. (Note: this is different from what you do for CliInitRun().)

This function is very similar to CliInitRun().
