fgetc, fgetwc, _fgetchar, _fgetwchar

Read a character from a stream (fgetc, fgetwc) or stdin (_fgetchar, _fgetwchar).

intfgetc(FILE*stream);

wint_tfgetwc(FILE*stream);

int_fgetchar(void);

wint_t_fgetwchar(void);

Return Value

fgetc and _fgetchar return the character read as an int or return EOF to indicate an error or end of file. fgetwc and _fgetwchar return, as a wint_t, the wide character that corresponds to the character read or return WEOF to indicate an error or end of file. For all four functions, use feof or ferror to distinguish between an error and an end-of-file condition. For fgetc and fgetwc, if a read error occurs, the error indicator for the stream is set.

Parameter

stream

Pointer to FILE structure

Remarks

Each of these functions reads a single character from the current position of a file; in the case of fgetc and fgetwc, this is the file associated with stream. The function then increments the associated file pointer (if defined) to point to the next character. If the stream is at end of file, the end-of-file indicator for the stream is set. Routine-specific remarks follow.

For more information about processing wide characters and multibyte characters in text and binary modes, see Unicode Stream I/O in Text and Binary Modes.

Example

/* FGETC.C: This program uses getc to read the first
 * 80 input characters (or until the end of input)
 * and place them into a string named buffer.
 */
#include <stdio.h>
#include <stdlib.h>
void main( void )
{
  FILE *stream;
  char buffer[81];
  int i, ch;
  /* Open file to read line from: */
  if( (stream = fopen( "fgetc.c", "r" )) == NULL )
   exit( 0 );
  /* Read in first 80 characters and place them in "buffer": */
  ch = fgetc( stream );
  for( i=0; (i < 80 ) && ( feof( stream ) == 0 ); i++ )
  {
   buffer[i] = (char)ch;
   ch = fgetc( stream );
