- NAME
- SyncRun -- Run a process and wait for its completion.
-
- SYNOPSIS
- rc = SyncRun( "Filename", "args", Input, Output)
- d0 a0 a1 d0 d1
-
- FUNCTION
- SyncRun loads a program from disk, searching the users Path
- as set by the Path command, run it, and return the exit
- status of the program to you, after first unloading the
- program. You may set the default Input and Output handles
- for the new process, if you supply NULL, the new process
- will inherit your processes default input and output.
-
- This function has been made as safe as possible, all task
- private data stored before the new process gets your TCB,
- and it is restored on exit. Furthermore, this function
- cooperates with arp.library's tracking functions to preserve
- your ResList and resources as well as correctly handling the
- new tasks calls to the tracking functions, if any are made.
-
- BCPL programs contain bugs which cause them to be inable to
- receive command lines from this function. All the programs
- from the rest of the world will receive their command lines
- just fine, as well BCPL programs when they decide to join
- the rest of us.
-
- INPUTS
- "Filename" -- the filename of the process you wish to load
- and run. The directory search path will be searched
- for this name.
-
- "Arguments" -- The arguments you wish to pass to this
- process. Note that the arguments are passed without
- parsing, so you should not expect io_redirection ( <
- > ) to work.
-
- Input -- The standard input for the new process. If zero, it
- will inherit your processes default input. This
- filehandle must be obtained and released by you.
-
- Output -- The standard output for the new process. If zero,
- it will share your processes default output. This
- filehandle must be obtained and released by you.
-
- RESULT
- If the return from this function is positive or zero, it is
- the return code of the process executed. ZERO means
- succesful termination.
-
- If the result is negative, this function is returning an

- error to you indicating that it could not execute or load
- the process.
-
- New for V33
- This function now releases memory chained into the tasks
- memlist by the child. Any memory allocated by the parent is
- of course not freed until exit.
-
- This function calls LoadPrg() to obtain the segment to run.
- This is a V33 function which searches first the
- ResidentList, then the user speced path.
-
- BUGS
- CLI programs only may use this function, it will return an
- error if a WorkBench or other process attempts to call it.
