Attempting to open more than the maximum number of file descriptors or file streams causes program failure. Use _setmaxstdio to change this number. File-Handling Routines (File Descriptor) These routines operate on files designated by a file descriptor File Handling concept in C language is used for store a data permanently in computer. Using this concept we can store our data in Secondary memory (Hard disk). All files related function are available in stdio.h header file. How to achieve File Handling in C. For achieving file handling in C we need follow following steps. Naming a file; Opening a file The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. The functionality descends from a portable I/O package written by Mike Lesk at Bell Labs in the early 1970s, and officially became part of the Unix operating system in Version 7..

For example, part of the disk might be. Further, the file handle argument appears after the string, which is unusual for a C language file function. The two file-writing functions fprintf() and fputs() write text to the file sequentially, one character after the other. The process works just like writing text to the screen, but instead those characters are saved in a file in permanent storage. The fgets() function reads an entire.
