Read a character from a stream (fgetc) or stdin (_fgetchar).
#include <stdio.h>
int fgetc( FILE *stream );
int _fgetchar( void );
| stream | Pointer to FILE structure |
The fgetc function reads a single character from the current position of the file associated with stream. The character is converted and returned as an int. The function then increments the associated file pointer (if any) to point to the next character. The _fgetchar function is equivalent to fgetc(stdin).
The fgetc and _fgetchar routines are identical to getc and getchar, but they are functions rather than macros.
The fgetc and _fgetchar functions return the character read. They return EOF to indicate an error or end-of-file. Use feof or ferror to distinguish between an error and an end-of-file condition.
