pdebug
QNX SDP8.0Utilities ReferenceUtilities
Process-level debugger
Syntax:
pdebug [-1aeflsv] [-n priority_levels] device
Runs on:
QNX OS
Options:
- -1
- (
One
) Exit pdebug after the debugging session is done. - -a
- Don't disable address space layout randomization (ASLR). The default is to disable it.
- -e
- Echo the debugged program's stdin back to the host.
- -f
- Run pdebug as a foreground process.
- -l
- (
el
) By default, pdebug sets the LD_BIND_NOW to 1 to force all binding to be done immediately instead of lazily. To permit lazy binding, specify the -l option. For more information, seeOptimizing the runtime linker
in the Compiling and Debugging chapter of the QNX OS Programmer's Guide. Immediate binding is the default. - -n priority_levels
- Be nice; set the debugged program's priority to be priority_levels lower than pdebug's. Doing this can keep pdebug from becoming unresponsive if the debugged process misbehaves (e.g. looping in a tight loop taking lots of CPU time).
- -s
- Notify the host only of signals caused by faults.
- -v
- Be verbose.
- device
- The device to use for the remote debug protocol; one of:
-
- Use stdout / stdin.
- /device_name[,baud]
- Open and use the specified device, such as /dev/ser1, optionally setting the baud rate.
- number
- Accept connections on TCP/IP port number.
Description:
This utility provides access to process-level debugging from a remote host, including from the IDE. To use pdebug, you need to run devc-pty on the target machine (i.e. the machine being debugged).
Examples:
For a 57600 baud serial connection on /dev/ser2:
pdebug /dev/ser2,57600 &
For a TCP/IP connection on port 8000:
pdebug 8000 &
