Embedded Xinu, Copyright (C) 2008, 2009, 2010, 2013, 2018. All rights reserved. This code while usually running is a work in progress .. AKA Alpha. It is walking a line between staying functional as well as being able to make the large changes required on the code base. I am updating the Wiki as I go if you do want to track what I am working on. The code has been altered to allow either orginal soft FPU compiling or now hard FPU compiling ... Please see notes. Default is set for hard float of the repository. I changed the makefile to build object files to a single directory so I could make the clean process faster. I hopefully added make under linux support in at the same time (untested). Compiling of ARM7(Pi2) and ARM8(Pi3) 32 bit code added as close to release (1 bug in ethernet driver). As the FPU is offline in code due to restriction with context switcher code there is little advantage right now. For stability stay with kernel.img although the other binaries are precompiled out of interest. Version: 3.00 Alpha the background.

Decrementing Initialization of a For Loop (C) - EX: for(i--; i>0; i--)

QUESTION

Decrementing Initialization of a For Loop (C) - EX: for(i--; i>0; i--)

Asked 2021-Nov-27 at 21:42

I have been reading about operating system design in the book, "The Xinu Approach 2nd Ed.", and came across a for loop statement in chapter 10 on page 182/183. The for loop starts off decrementing the initialization statement of the for loop. I hadn't seen this before, so I created my own version of this loop to play around with it, as seen here:

...

In your version of the loop you print the '\r' character. This is a carriage return character. The result is that printf overwrites already written characters. Please see this question: What's the Use of '\r' escape sequence?

Vulnerabilities

No vulnerabilities reported

Install Xinu

It should be as simple as download a C compiler for your O/S I am using the ARM standard toolset in the useful link list down the page. Download a make executable (make.exe) for your O/S .. On windows I am using GNU make 4.21. Place the binary directories for the compiler and makefile on your path environment. Open a command console and navigate to the compile directory on your copy of the repository Issue the command make. It should start building away :-).
make clean ... will remove all the temp compiled binary object files which forces a full build
make libclean ... will remove all the temp compiled library files so the library can be rebuilt.
