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 back-
       end  only guarantees a single pushback; this depends on the libc	imple-
       mentation.

       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)
