fgetc, fgetwc (Windows CE 5.0)
Developing an Application > Microsoft C Run-time Library for Windows CE > Run-time Library Reference
Read a character from a stream.
int fgetc( FILE*stream);wint_t fgetwc( FILE*stream);
Parameters
- stream
Pointer to FILE structure.
Return Values
fgetc returns the character read as an int or return EOF to indicate an error or end of file.
fgetwc returns, 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 both functions, use feof or ferror to distinguish between an error and an end-of-file condition.
For both functions, if a read error occurs, the error indicator for the stream is set.
Remarks
Each of these functions reads a single character from the current position of a file. 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.
| Routine | Remarks |
|---|---|
| fgetc | Implemented only as a function, rather than as a function and a macro. |
| fgetwc | Wide-character version of fgetc.
Reads c as a multibyte character or a wide character according to whether stream is opened in text mode or binary mode. |

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 );
}
/* Add null to end string */
buffer[i] = '\0';
printf( "%s\n", buffer );
fclose( stream );
}
Output
/* FGETC.C: This program uses getc to read the first
