I have been trying to explore the source code of the getcontext() and setcontext functions but I have not been able to spot the right file or resource. Any help in this regard will be helpful.
I was able to trace to http://fossies.org/dox/glibc-2.14.1/setcontext_8c_source.html but there is no info
These are system functions related to setjmp/longjmp instructions. They are probably part of the glibc library (just a guess). Look on the GNU web site (gcc) for the source code. According to the comments in /usr/include/ucontext.h (the header file for these instructions), it is part of the GNU C library, as I surmised.
I also posted it in the other forums. I was forwarded to the asm code for these functions. But these are difficult to follow http://www.koders.com/noncode/fid466DE9347BF79B388783D3F5D94BAF6748F618C9.aspx?s=readdir64 and http://www.koders.com/noncode/fid62EE9446C4DEED004E74CD6D61D7C81435E413FE.aspx?s=queue . I am always ready for the other sources ! :)
