C Valid File Descriptor at Megan Boyd blog

C Valid File Descriptor. Each open file, pipe, or other resource consumes one file descriptor. So let’s discover how the operating system handles. Given an open file descriptor, you can create a stream for it with the fdopen function. The available system calls to create or open, read, write, and delete a file in c all make use of a file descriptor. Both file descriptors and streams can represent a. Fcntl(getfl) is probably the cheapest and least likely to fail operation you can perform on a file descriptor, so i've chosen it. A file descriptor is what is returned by the open () function after it has been used to open a file. This section describes the primitives for opening and closing files using file descriptors. You can get the underlying file. The open and creat functions are declared in the header. Once that is done, we may utilize this file descriptor. Fcntl(fd, f_getfd) is the canonical cheapest way to check that fd is a valid open file descriptor. Here are some standard file descriptor values:
