Process Data Structures

These values are created as part of an AmigaDOS process; there is a complete set for each process.

A process is an Exec task with a number of extra data structures appended. The process structure consists of:

The process identifier AmigaDOS uses internally is a pointer to the Exec message port (pr_MessagePort) from which the Exec task may be obtained.

AmigaDOS process values are as follows:

Type	Name	Description
BPTR	pr_SegList	Array of seg lists used by this process
LONG	pr_StackSize	Size of process stack in bytes
APTR	pr_GlobVec	Global vector for this process (BCPL)
LONG	pr_TaskNum	CLI task number of zero if not a CLI
BPTR	pr_StackBase	Ptr to high memory end of process stack
LONG	pr_Result2	Value of secondary result from last call
BPTR	pr_CurrentDir	Lock associated with current directory
BPTR	pr_CIS	Current CLI Input Stream
BPTR	pr_COS	Current CLI Output Stream
APTR	pr_ConsoleTask	Console handler process for current window
APTR	pr_FileSystemTask	File handler process for current drive
BPTR	pr_CLI	Pointer to CLI
APTR	pr_ReturnAdd	Pointer to previous stack frame
APTR	pr_PktWait	Function to be called when awaiting msg
APTR	pr_WindowPtr	Window for error printing
