prototype is size_t fread (void * PTR, size_t size, size_t N, file * stream). The PTR parameter stores the read data, void * pointers can be replaced by pointers of any type, such as char * and int *. Size indicates the number of bytes in each block. N indicates the number of read blocks. If yes, returns the number of actually read parts (not the number of bytes). This function is generally used in files opened in binary mode. Example: Char X [4230]; File * file1 = fopen ("C: \ msdos. sys

settings. Click settings to select the computer serial port to be used. Keil μ vision2 is set to COM1/9600 by default. The simulator is adaptive to the serial communication baud rate within a certain range. When the crystal oscillator frequency is 11.0592mhz, the baud rate can be between 4800 and ~ Select between 38400. Generally, the maximum value is used to increase the speed of serial communication. See Figure 6. Click OK to save the settings. The simulator or target board can also s

The prototype is size_t fwrite (const void * PTR, size_t size, size_t N, file * stream ); the PTR parameter is the data pointer to be written. The Void * pointer can be replaced by any type of pointer,

reconfigure a new one based on the size. in this way, there will be no waste of space. As for the meaning of the above-mentioned members of the comatrix drop structure, the on-line help should be fully written. 4. Set and obtain the communication status You can get some status by using comatrix drop, but when you want to change the current settings, you need two APIs: Bool getcommstate (Handle hfile, // handle of communications deviceLpdcb // address of device-Control Block Structure

the obstacle (mixed line, broken line, ground gas, etc ). The trunk cable can contain up to 2400 pairs of copper wires. The trunk cable is divided into two types: oil filling and inflation. Fill the cable jacket with oil or gas to prevent moisture from being immersed in the core line. The inflatable model also requires a complete set of inflation system maintenance equipment. The transfer box is actually a micro distribution frame, which is responsib

Enjoy There are courses around the world to teach people how to flirt. A German university even asks its IT engineers to take flirting courses-not to attract partners, but to learn how to communicate more effectively at work. At first glance, it seems a little "Frivolous", but here flirting means establishing connections with others, and communication is

The loose pair is different from the tight pair. Two people don't always sit together to locate the problem and solve the problem at any time, but sit together for a short time. There are two main tasks at the post-Checkpoint: one is to check whether the results meet the requirements (what to do), the other is to check whether the code is faulty (how to do it), and the other is to check the code. Code check (also known as code review code inspection) is a long-standing but mysterious thing. It w

. The system antenna is a micro-antenna, so the antenna can be small in size and light in quality. The air interface is based on the antenna level of 0 dBm and complies with the FCC (Federal Communications Commission) ISM band standard with the level of 0 dBm. Because Bluetooth uses the frequency hopping technique, the antenna must be a broadband antenna with a frequency starting from 2.402 GHz and a frequency ending from 2.480 GHz. To resist multi-path interference, the system is designed as a

traditional hard disks. The storage unit addressing overhead is greatly reduced because of the high iops. Memory Analysis Why can't SSD achieve memory access speed? This is because the implementation principle of the RoM SSD and RAM memory is different. The memory development speed has reached the fifth-generation DDR memory (usually used on graphics cards), and we usually use the third-generation DDR memory on the motherboard, the main memory indicators are read/write/bandwidth, while the i

A Japanese scientist claims to have listed 2400 applications for paper clips. A scholar in Nanjing declared that he could list 30 thousand types!How many uses does a paper clip have?As long as you are willing to find it, do you agree that the answer is: countles

management settings, each fast controller has an RJ45 network cable port, and is configured through the network. Each controller also has a stringPort. You can modify the IP address through the serial port. Insert a section into the RS-232 of Controller A, and the other end is connected to another windows2000/NT4.0 machine serial port. After completing the settings, connect to Controller B and perform the same operation. The following uses ds4200 as an example and illustrates the configuration

, it is only 29.8 astronomical units from the sun, closer than Neptune. The orbital angle is 17.1 °, which is much larger than other major stars. The average orbital speed is 4.74 km/second, and it takes 248 to go public for a week. Based on the variation in the brightness of Pluto's surface, it can be measured that its rotation cycle is 6 days, 9 hours, 17 minutes. The angle between the self axis and the Public axis of Pluto is greater than 60 °, so it is similar to the lateral rotation of Uran

do not like thick and tedious product manuals. They generally like to explore the product after purchasing a digital camera. Of course, there will be some surprises during the exploration process, but it will take a lot of time, and you cannot learn the features of your products in the shortest time; if you have read the instructions, you can avoid some errors. Therefore, when you are new, you should first look at the instructions carefully compiled by the manufacturer to familiarize yourself w

calendar in use today, years evenly divisible by 4 are leap years, with the exception of Centurial years that are not evenly divisible by 400. therefore, the years 1700,180 0, 1900 and 2100 are not leap years, But 1600,200 0, and 2400 are leap years. Given the number of days that have elapsed since January 1, 2000 A.D, your mission is to find the date and the day of the week.
