LINUX tracking [code] If (pcap_loop (pds[myint], pv.pkt_cnt (pcap_handler) ProcessPacket, NULL) "0)     { If (pv.daemon_flag) Syslog (LOG_CONS | LOG_DAEMON, "pcap_loop : %s" pcap_geterr (pd)); Else ErrorMessage ( "pcap_loop : %s" pcap_geterr (pd)); CleanExit (SIGQUIT);     } The question is : is a function ProcessPacket when entering the circle, I would like to use LINUX operating procedures for tracking, I set up breakpoint ProcessPacket function, but he kept! Will be how do? [/code] LINUX tracking ProcessPacket there is a definition of function, it will not make the original documents into g LINUX tracking LINUX tracking Printf function for example, the system can also be set up breakpoint, but could not enter debugging, (Gdb) b printf Breakpoint 1 at 0x2830 : file cow.c, line 1. (Gdb) LINUX tracking --> Oh, it was the first time I noticed, thank you. LINUX tracking Concern. . . Could do with the function pointer parameters. LINUX tracking This function can be found in the code? ProcessPacket if we can find the following approach. ProcessPacket together with the code? {int I=1; My_log ( "gdb me, i have run this. Pid[%d] ", getpid ()); While (i) ( Usleep (0);    } } Operating procedures. This procedure will be stopped from the diary found pid (ps or what)? Get procedures were pid Pi Set var ≥ That could be implemented after the next! This method commonly used in multi-process debugging! Concern. . . Up [ Closed window ]
