【gdb】同时调试父进程和子进程

设置读观察点1.例子#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;void*thread1_func(void*p_arg){while(1){a++;sleep(10);}}void*thread2_func(void*p_arg){while(1){a++;sleep(10......

设置读写观察点1.例子：#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;void*thread1_func(void*p_arg){while(1){a++;sleep(10);}}void*thread2_func(void*p_arg){while(1){a++;sleep(1......

输出信息多时不会暂停输出有时当gdb输出信息较多时，gdb会暂停输出，并会打印“---Type<return>tocontinue,orq<return>toquit---”这样的提示信息，如下面所示：81process26391020xff04af84in__lwp_park()from/usr/lib/libc.so.180process25735660xff04......

显示gdb版本信息使用gdb时，如果想查看gdb版本信息，可以使用“showversion”命令:(gdb)showversionGNUgdb(GDB)7.7.1Copyright(C)2014FreeSoftwareFoundation,Inc.LicenseGPLv3+:GNUGPLversion3orlater<http://gnu.org/licenses/gpl.html>Thisisfreesof......

启动时不显示提示信息$gdbGNUgdb(GDB)7.7.50.20140228-cvsCopyright(C)2014FreeSoftwareFoundation,Inc.LicenseGPLv3+:GNUGPLversion3orlater<http://gnu.org/licenses/gpl.html>Thisisfreesoftware:youarefreetochangeandredistributeit.The......

gdb退出时不显示提示信息gdb在退出时会提示:Adebuggingsessionisactive.Inferior1[process29686]willbekilled.Quitanyway?(yorn)n如果不想显示这个信息，则可以在gdb中使用如下命令把提示信息关掉:(gdb)setconfirmoff也可以把这个命令加到.gdbi......

只允许一个线程运行1.例子：#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;intb=0;void*thread1_func(void*p_arg){while(1){a++;sleep(1);}}void*thread2_func(void*p_arg){while(1){b+......

调试子进程1.例子#include<stdio.h>#include<sys/types.h>#include<unistd.h>intmain(void){pid_tpid;pid=fork();if(pid<0){exit(1);}elseif(pid>0){exit(0);}printf("helloworld\n&qu......
