You want the process that sends the data to run in the background, but this problem occurs when you start the process.In general, this problem may be related to the following reasons:"[1] + Stopped (TTY input)" means that the program tries to read from the control terminal, but is stopped by the sigttin signal because it is running in the background:The man signal has the following output:Sigttin Stop process Background read attempted from Control terminalThe following program demonstrates this

The difference between QNX and linux-general Linux technology-Linux technology and application information. The following is a detailed description. I am now studying the QNX operating system. Although it is QNX, it actually has a

with CPU cores such as PowerPC and MIPS as the core. QNX operating systems comply with POSIX basic and real-time standards, so that their applications can be easily transplanted. QNX has many advantages. Compared with Windows and Linux, QNX is faster and the interface is more elegant. Compared with other systems,

QNX is a real-time operating system developed by QNX software system Ltd. (qssl) in Canada based on micro-kernel and full address space protection, real-time, distributed, multi-task, and modular cropping. It complies with POSIX standards and is one of the few real-time operating systems that support graphic user interfaces. The QNX kernel only provides the most

The embedding process of QNX is generally: Build buildfile-> compile buildfile to generate the system image file-> Start the target system-> Design the embedded system software. The key is to build buildfile [19]. Generally, an embedded system requires an operating system image file that can be started ). For a QNX-based embedded application system, the embedded system is customized based on the selected C

QNX is a UNIX-like real-time operating system that complies with POSIX specifications and has good portability. Writing any driver has the same problem: how the application interacts with the driver. In fact, this problem is very simple. QNX has a lot of information to illustrate this point. This problem occurs when the client calls FD = open ("Dev/mydevice", o_rdwr) to open the device mydevice and expects

BKJIA Editor's note: A blue ray of the sky, RIM's BlackBerry is a little overwhelmed by the aggressive trend of iOS and Android. According to BGR, the BlackBerry QNX system program is developed with Dalvik! Dalvik is a Java Virtual Machine for Android, and Android applications are developed using Dalvik! BGR, which has always been reliable in BlackBerry messages, reported yesterday that there are multiple reliable sources telling them that RIM is s

program.So how do you write an interrupt in QNX? QNX offers two ways to connect interrupts:int interruptattachevent (int intr, const struct sigevent *event, unsigned flags);int Interruptattach (int intr, const struct sigevent * (*handler) (void *arg, int id), const void *area, int size, Unsigne D flags);where int intr represents the interrupt vector number, it is written in the data sheet when the pic is i

As we all know, QNX is a micro-core operating system that relies on interprocess communication to achieve the entire system function. So specifically to write a program, exactly how this communication is done? This chapter is specific to the bottom of the message delivery API. Message passing is done through the kernel, so the so-called API, which is actually the lowest-level kernel call. It should be noted that when you really write programs on
