-/* Use these functions to avoid a warning when using a function declared with
- gcc's warn_unused_result attribute, but for which you really do want to
- ignore the result. Traditionally, people have used a "(void)" cast to
- indicate that a function's return value is deliberately unused. However,
- if the function is declared with __attribute__((warn_unused_result)),
- gcc issues a warning even with the cast.
-
- Caution: most of the time, you really should heed gcc's warning, and
- check the return value. However, in those exceptional cases in which
- you're sure you know what you're doing, use this function.
-
- For the record, here's one of the ignorable warnings:
- "copy.c:233: warning: ignoring return value of 'fchown',
- declared with attribute warn_unused_result". */
