The _fpurge() function requests that any pending data in the stream be discarded.

In the context of streaming video or audio, buffering is when the software downloads a certain amount of data before it begins playing the video or music. <\/p>\n<h3><span class=\"ez-toc-section\" id=\"Declaring_a_Buffer\"><\/span>Declaring a Buffer<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>How do you declare a buffer? Declare a buffer size, traditionally a power of two, like 2048, and read the file into it in chunks, then run your logic on the chunk each time you read a block. You then use constant memory, can read any size file, and don&#8217;t have to guess.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Output in C Programming When we say Output, it means to display some data on screen, printer, or in any file.
