int

c

)

The explain_putchar_on_error function is used to call the putchar(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_putchar(3) function.

This function is intended to be used in a fashion similar to the following example:

 if (explain_putchar_on_error(c) == EOF)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

c	The c, exactly as to be passed to the putchar(3) system call.

Returns:

The value returned by the wrapped putchar(3) system call.
