Webfwrite() 是 C 语言标准库中的一个文件处理函数，功能是向指定的文件中写入若干数据块，如成功执行则返回实际写入的数据块数目。该函数以二进制形式对文件进行操作，不局限 … WebTo turn a bit on: data = 1 << bitNumber; The right-hand side ( 1 << bitNumber) is a bit-shift operation to create a suitable bit-mask. It takes the single '1' bit and moves it left until it reaches the desired position. The bitwise-or assignment ( =) combines that new bit-mask with the existing bits in data. This turns the desired bit on, but ...
