fwrite c

The fwrite function in C is used to write data to a file. Its syntax is:

size_t fwrite(const void ptr, size_t size, size_t nmemb, FILE stream);

Where: - ptr: Pointer to the array of elements to be written. - size: Size in bytes of each element to be written. - nmemb: Number of elements, each one with a size of size bytes. - stream: Pointer to a FILE object that specifies the stream where the data is to be written.

The fwrite function returns the number of full elements successfully written, which may be less than nmemb if an error occurs.
