The Client uses bidirectional communication such that it is possible to set commands to the bodies and at the same time to read their states using a library of Python functions. These functions are used, for example, to set or get the position and orientation of bodies as well as control the wrench acting on a body or get the number of joints ...
Kqueue not only handles file descriptor events but is also used for various other notifications such as file modification monitoring, signals, asynchronous I/O events (AIO), child process state change monitoring, and timers which support nanosecond resolution, furthermore kqueue provides a way to use user-defined events in addition to the ones ...
The documentation of perf is not very detailed (as of 2014); for example, it does not document most events or explain their aliases (often external tools are used to get names and codes of events [15]). [16] Perf tools also cannot profile based on true wall-clock time., [16] something that has been addressed by the addition of off-CPU profiling.
For each crontab file found, determine the next time in the future that each command must run. Place those commands on the Franta–Maly event list with their corresponding time and their "five field" time specifier. Enter main loop: Examine the task entry at the head of the queue, compute how far in the future it must run.
Expect is an extension to the Tcl scripting language written by Don Libes. [2] The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems.
watch is a command-line tool, part of the Linux procps and procps-ng packages, that runs the specified command repeatedly and displays the results on standard output so the user can watch it change over time. By default, the command is run every two seconds, although this is adjustable with the -n secs argument.
A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.
The SIGLOST signal is sent to a process when a file lock is lost. SIGSTKFLT The SIGSTKFLT signal is sent to a process when the coprocessor experiences a stack fault (i.e. popping when the stack is empty or pushing when it is full). [23] It is defined by, but not used on Linux, where a x87 coprocessor stack fault will generate SIGFPE instead ...
