I just want to ask, I know that standart system calls in Linux are done by int instruction pointing into Interrupt Vector Table. I assume this is similiar on Windows. But, how do you call some higher-
Is there a way to have a bit bucket pointer? A lot of IO (specifically input related) system calls return data to a buffer of a specific size. Is there a trick or way to make a sorta bit bucket point
Whe开发者_如何学编程re are some lists of system calls on UNIX? This wasn\'t my original question, but thanks anyway :)man 2 syscalls
I want to write a signal handler to catch SIGSEGV. I protect a block of memory for read or write using
I use syscall S开发者_StackOverflowYS_time, but its resolution is 1 second. Is there any other solution?Try clock_gettime(3R) (same for Linux). I have to dig up the assembly version for the calls.
I wanted to try out the splice syscall. I have this function - it should copy content of one file to another:
I have a long list of all the calls a program I have does. What i need to know is which DLL each call belongs t开发者_开发百科o. How would I find this out?
I\'m doing some experimenting and would like to be able to see what is saved on the stack during a system call (the saved state of the user land process). According to http://lxr.linux.no/#linux+v2.6.
I am trying to understand why this design decision was made with the rename() syscall in 4.2BSD.There\'s nothing I\'m trying to solve here, just understand the rationale for the behavior itself.
I\'m trying to figure out how to get a list of and documentation for the system calls available in the XNU kernel in OSX.I\'ve go开发者_运维技巧ogled around quite a bit, but haven\'t been able to find
