Function Documentation

int explain_ftime_on_error

(

struct timeb *

tp

)

The explain_ftime_on_error function is used to call the ftime(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_ftime(3) function.

Parameters:

tp	The tp, exactly as to be passed to the ftime(3) system call.

Returns:

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

Example:

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

 if (explain_ftime_on_error(tp) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

This function only returns on success, see ftime(3) for more information. On failure, prints an explanation and exits, it does not return.
