Sand-breaking potOpen source GDB is widely used in Linux, OSX, UNIX and various embedded systems (such as mobile phones), this time it brings us a surprise.The pain of multi-threaded debuggingDebuggers (such as VS2008 and older gdb) tend to support

Debugging a Python process with gdb sometimes we want to debug a running Python process, or a Python process coredump. For example, now encountered a MOD_WSGI process zombie, do not accept the request, want to see exactly what line of Python code to

Before you start running the program in GDB, you need to generate debugging information at compile time.You can start gdb with parameters (if any) in your chosen environment. If you are debugging locally, you can redirect the input output, debug a

_____main function contains two parameters, ARGC, argv[]These two parameters are used to indicate the parameter information entered by the command line.The value of the ARGC is the number of input parameters. ARGV is an array in which each array

First, GDB changes the execution of the programOnce you use GDB to hang up the debugger, when the program is running, you can change the running line of the currently debugged program or the value of its variable dynamically in GDB according to your

There are compiled general type similar stack programs, namely Piles. h and Piles. c. The header files are listed here, mainly to understand the call method:# Ifndef PILE_H# Define PILE_H# Include Typedef struct _ pile * Pile;Typedef enum

Formatted read/write: # Include Int printf (const char * format,...); // equivalent to fprintf (stdout, format ,...); Int scanf (const char * format ,...); Int fprintf (FILE * stream, const char * format,...); // The intermediate parameter is the

Because the ET pattern needs to be read in a loop, but during the reading process, if a new event arrives, it is likely that another thread is triggering the socket to handle it, which is a mess.Epoll_oneshot is used to avoid this situation. Note
