al_fungetc(3)		    Library Functions Manual		   al_fungetc(3)

NAME
     al_fungetc - Allegro 5 API

SYNOPSIS
	    #include <allegro5/allegro.h>

	    int al_fungetc(ALLEGRO_FILE *f, int c)

DESCRIPTION
     Ungets a single byte from a file.	Pushed-back bytes are not written to the
     file, only made available for subsequent reads, in reverse order.

     The  number  of pushbacks depends on the backend.	The standard I/O backend
     only guarantees a single pushback; this depends on the libc implementation.

     For backends that follow the standard behavior, the pushback buffer will be
     cleared after any	seeking  or  writing;  also  calls  to	al_fseek(3)  and
     al_ftell(3)  are relative to the number of pushbacks.  If a pushback causes
     the  position  to	become	negative,  the	behavior  of   al_fseek(3)   and
     al_ftell(3) are undefined.

SEE ALSO
     al_fgetc(3), al_get_errno(3)
