If you want to redirect, you can use POSIX function dup/dup2. They of course won't work on Windows OS (after adding the POSIX package from Microsoft, they might, but I'm not a Windows expert).

I am writing a crash debug mechanism which requires me to execute the VxWorks routines like i, taskShow etc in the Exception Handler context. I would have opted to redirect the output to a file in the flash device, but this is time consuming. Is there a way in which I can redirect the output to a memory buffer.<br />

Thanks<br />

How do I redirect the stdout to a memory buffer. Technology C,VxWorks

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
