Standard library header <stdio.h>

From cppreference.com
< c‎ | header
 
 
 

This header is part of input/output library, providing generic file operation support and supplies I/O functions that work with narrow characters.

This section is incomplete
Reason: 7.23 Input/output <stdio.h>; copy/share subset of c/io
