Linux Can File Descriptor Be 0 at Kai English blog

Linux Can File Descriptor Be 0. The strcat() function concatenates two char strings and then uses an i/o stream using file descriptor 1. File descriptor 0 isn't really “attributed to stdin” — rather, it is stdin by definition of stdin. A file descriptor is a reference to an open file description; At the file descriptor level, stdin is defined to be file descriptor 0, stdout is defined to be file descriptor 1; Using explicit file descriptors becomes useful when you want to write to multiple files in turn. Here we are reading characters from stdin by using file descriptor 0 [ read() at line 7 ] and then after concatenating it with a message [ strcat() at line 8 ] and then. In linux, there are three types of file descriptors that are commonly used by programs and commands: This reference is unaffected if pathname is subsequently removed or modified. Finally, it pushes the output with the write() function using the file descriptor 1. For example, consider a script that outputs data to. The read(0, buff, 20) function uses the stdin using file descriptor 0. And stderr is defined to be file. Standard input (stdin), standard output (stdout), and standard error (stderr).
