C语言 分割字符串

对指针的操作有点迷糊
只好采用下面一些比较low的手段

			char str[100];
			char delims[] = ";";
			char *result = NULL; 			
			sprintf(str,"%s",USART_RX_BUF);			
			result = strtok( str, delims ); 
			while( result != NULL ) { 
					printf( "result is \"%s\"\n", result ); 
					result = strtok( NULL, delims ); 
			}

有时间再看看用指针怎么弄
