Reads a character from a stream (getc), or gets a character from stdin (getchar).
#include <stdio.h>
int getc( FILE *stream );
int getchar( void );
| stream | Current stream |
The getc routine reads a single character from the stream position and increments the associated file pointer (if there is one) to point to the next character. The getchar routine is identical to getc(stdin).
The getc and getchar routines are similar to fgetc and _fgetchar, respectively, but are implemented both as macros and functions.
Both getc and getchar return the character read. A return value of EOF indicates an error or end-of-file condition. Use ferror or feof to determine whether an error or end-of-file occurred.
