1. Elegant and safe way to determine if architecture is 32bit or 64bit    stackoverflow.com

As title says, is there any elegant and safe way to determine if architecture is 32bit or 64bit. By elegant, you can think of precise, correct, short, clean, and smart way. ...

2. An issue of C in 64 bit architecture: pthread_kill()    stackoverflow.com

The question is quite simple: my application runs perfectly on a 32 bit architecture, but on a 64 bit arch. I got segmentation fault. I guess that the cause is the ...

3. Compiling and Linking a C-Program for a 32-bit Architecture    stackoverflow.com

So I'm working through an assignment for Stanford's CS107 course and I can't get past compiling the unfinished program (project files and the original makefile can be found on ...

4. Conditional compilation depending on 32-bit or 64-bit architecture    bytes.com

Hi, I am trying to write some code which acts differently when compiled on 32 bit and 64 bit machines. To identify the machine type, I am trying to find the sizeof( int ) and comparing it with 32 and 64. But, the compiler is complaining about syntax errors in the #if lines. Errors: 32-64.cpp:7:13: missing binary operator before '(' 32-64.cpp:12:13: ...

5. Bit shifting versus architecture question.    bytes.com

I understand different processor hardware may store the bits in a byte in different order. Does it make a difference in C insofar as bit-shifting unsigned char variables is concerned? E.g, if I have unsigned char x = 1; is it always true that (x << 1) == 2 (x << 2) == 4 etc? Or might I have to reverse ...
