SegList |
|
Seglist of command to run. |
StackSize |
|
Number of bytes to allocate for stack space |
ArgPtr |
|
Pointer to argument command string. |
ArgSize |
|
Number of bytes in argument command string. |
Return code from executed command. -1 indicates failure
Runs a command on your process/cli. Seg may be any language, including BCPL programs. Stack is in bytes. paramptr is a null- terminated string, paramlen is its length. Returns the returncode the program exited. Returns -1 if the stack couldn't be allocated.
NOTE: the argument string must be terminated with a newline to work properly with ReadArgs() and other argument parsers.
RunCommand also takes care of setting up the current input filehandle in such a way that ReadArgs() can be used in the program, and restores the state of the buffering before returning. It also sets the value returned by GetArgStr(), and restores it before returning.
It's usually appropriate to set the command name (via SetProgramName()) before calling RunCommand(). RunCommand() sets the value returned by GetArgStr() while the command is running.
