fgetchar

get a character from stdin

Synopsis:

#include <stdio.h>
int fgetchar( void );

Description:

The fgetchar() function is equivalent to fgetc() with the argument stdin.

Returns:

• The fgetchar() function returns the next character from the input stream pointed to by stdin.
• If the stream is at end-of-file, the end-of-file indicator is set, and fgetchar() returns EOF.
• If a read error occurs, the error indicator is set, and fgetchar() returns EOF. The global variable errno contains a value indicating the type of error that has been detected.

#include <stdio.h>

void main()
  {
    FILE *fp;
    int c;

    fp = freopen( "file", "r", stdin );
    if( fp != NULL ) {
      while( (c = fgetchar()) != EOF )
        fputchar(c);
      fclose( fp );
    }
  }
