fputc

int fputc ( int character, FILE * stream );
Write character to stream
Writes a character to the stream and advances the position indicator.

The character is written at the position indicated by the internal position indicator of the stream, which is then automatically advanced by one.

Parameters

character
The int promotion of the character to be written.
The value is internally converted to an unsigned char when written.
stream
Pointer to a FILE object that identifies an output stream.

Return Value

On success, the character written is returned.
If a writing error occurs, EOF is returned and the error indicator (ferror) is set.
