Bug ID: 89031
Summary: Should not report unused result when explicitly cast
to void
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: porton at narod dot ru
Target Milestone: ---
GCC reports unused result even when explicitly converted to void to show the
developer's intent not to report a warning.
lib.c: In function ‘libcomcom_run_command’:
lib.c:263:15: error: ignoring return value of ‘write’, declared with attribute
warn_unused_result [-Werror=unused-result]
(void)write(process.child[WRITE_END], &errno, sizeof(errno)); /*
deliberately don't check error */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Should not report unused result when explicitly cast to void.
