I\'m writing a MIPS32 emulator and would like to make it possible to use the whole Standard C Library (maybe with the GNU extensions) when compiling C programs with gcc.
How can I add a new libc function and also call it from C programs? The new function is a not a wrappe开发者_如何学Gor to any kernel level system calls. Its function will be done in user space.Put it
I invoked getpid() in a program for many times (to test the efficiency of system calls), however when I use strace to get the trace, only one getpid() call is captured.

I sometimes hear people using the terms \"libc\" and \"C standard library\" interchangeably. I understand that \"libc\" is the name (or part of the names) of many popular C standard library implementa
I\'d like to profiling my owned process in target hardware, I only can check the source code as libc.so since there is no libc_p.so available for my开发者_开发百科 MIPS target hardware.
I started some socket programming, and I ran across the function inet_ntoa . The function has the prototype char * inet_ntoa(struct in_addr in);.
Will开发者_StackOverflow中文版 the gets()function from C language (e.g. from glibc) stop, if it reads a zero byte (\'\\0\') from the file ?
Consider the following code: #include <stdio.h> #include <time.h> #include <math.h> // Compile with gcc -lrt -lm -o test_clock test_clock.c
