尝试使用分隔符“”使用 strtok 拆分字符串，但出现段错误。
char command[12];
char *instruction;
char *parameter_1;
char *parameter_2;
*instruction = strtok(command, " ,.-");
*parameter_1 = strtok(NULL, " ,.-");
*parameter_2 = strtok(NULL, " ,.-");
write(1,parameter_1,sizeof(parameter_1));
在那个点
编辑: 根据要求，编译器警告。没有在任何地方使用 int，所以很困惑。

编辑 2:
int prompt() {
// Get Input
char inputData[256];
int rid;
rid = read(0,inputData,256);
// Strip input
char command[rid];
int i;
for (i = 0; i<=rid-2; i++) {
command[i] = inputData[i];
}
command[rid-1] = '\0';
// Debug
// printf("\n-%c-%i\n",command[10],(int)sizeof(command));
// write(1,command,sizeof(command));
if (strcmp(command, "exit") == 0) {
break;
}
char *instruction;
char *parameter_1;
char *parameter_2;
instruction = strtok(command, " ");
parameter_1 = strtok(NULL, " ");
parameter_2 = strtok(NULL, " ");
write(1,instruction,sizeof(instruction));
//write(1,parameter_2,sizeof(parameter_2));
}
return 0;
