Author: pfg Date: Tue Jan 9 22:48:13 2018 New Revision: 327751 URL: https://svnweb.freebsd.org/changeset/base/327751 Log: Use the __result_use_check attribute also for reallocf(3). The GCC attribute causes a warning to be emitted if a caller of the function with this attribute does not use its return value. Unlike the traditional realloc, with reallocf(3) we don't have to check for NULL values but we still have to make sure the result is used.
