[問題] strtok問題
請問
char copy[255];
cmnd = strtok(inpt," "); //get the first command
cmnd = strtok(NULL," ");
if(strncmp(cmnd,"<",1)==0)
｛
strcpy(copy,cmnd);
filename=strtok(copy,"<");
｝
cmnd = strtok(NULL," "); //go now to the next token for commands
printf("remain cmnd=%s\n",cmnd);
input為 cat <xx >333
以空白符號切cmnd=cat
再切cmnd=<xx
我把cmnd字元指標拷貝到copy字元陣列，以免動到cmnd，之後copy以<符號切
但是再切cmnd就沒東西，也就是remain cmnd=NULL，不是原來預期的＞333
為什麼會這樣？？？我明明把把cmnd字元指標拷貝到copy!!
是因為記憶體指向同個位置嗎?
