Int system () problem Why do I #include "Sys/types.h" Int main (void) { System ( "cd usr/acce/var"); Exit (0); } Unable to change the current list? ? ? Int system () problem Brothers, each process has a current catalog, but the process can influence a father son process. So ah, indeed to change the current system catalog, but it is to change the system deployed in the process of formation, and the shell or not. I humbly believe that programming to knock a few small changes to achieve the current list is not alphabetical (lazy pressure always think of only a few keys will be able to enter a long list). But I have a solution can be achieved : CDLOG= first [code]export "cd /usr/home/flw/chat/server/log" [/code] In this way, we can then reuse $CDLOG! Can also export sentence wrote. Profile, some of this easier. Int system () problem Indeed, we will not be able to see how the order cd system call!
