- push byte back into input stream
#include <stdio.h>intungetc(intc,FILE *stream);
Theungetc() function pushes the byte specified byc (converted to anunsigned char) back onto the input stream pointed to bystream. The pushed-backbytes will be returned by subsequent reads on that stream in thereverse order of their pushing. A successful intervening call (with the stream pointedto bystream) to a file-positioning function (fseek(3C),fsetpos(3C) orrewind(3C))discards any pushed-back bytes for the stream. The external storage corresponding tothe stream is unchanged.
Four bytes of push-back are guaranteed. Ifungetc() is called toomany times on the same stream without an intervening read or file-positioningoperation on that stream, the operation may fail.
If the value ofc equals that of the macroEOF, theoperation fails and the input stream is unchanged.
A successful call toungetc() clears the end-of-file indicator for the stream.The value of the file-position indicator for the stream after reading ordiscarding all pushed-back bytes will be the same as it was beforethe bytes were pushed back. The file-position indicator is decremented by each successfulcall toungetc(); if its value was 0 before a call, itsvalue is indeterminate after the call.
Upon successful completion,ungetc() returns the byte pushed back after conversion. Otherwise it returnsEOF.
No errors are defined.
