# The "info pid" and "-pid-info" commands were added for Xcode's benefit,
# so it can find the process ID of the inferior program via gdb.


## Test both "info pid" and the MI command "-pid-info" in three cases:

#  1. Before the inferior has started running.
#  2. While the inferior is running.
#  3. After the inferior has exited.

## Additionally, run the commands in console, mi1, and console-quoted
## interpreter modes to make sure all fo them work.  A little fancy
## regexping is necessary to switch between the modes, but it's not that
## bad.

# FIXME: There's a race condition in info-pid.exp, on the "switch to
# console quoted" test.  Since it uses mi_gdb_test, and the switch to
# console stuff ends up printing two GDB prompts, if only half of the
# response comes through in a given read(), it will match one of the
# mi_gdb_test failure cases instead of waiting for the rest of the
# data to come through.  At some point, we should clean up the
# prompt-printing part of the interpreter switching code.  In the
# meantime, we can use a specific test instead of mi_gdb_test.
