BUILD/MINOR: systemd: fix compiler warning about unused result
|
|||
|
|
|||
|
There is a compiler warning after commit 1b6e75fa84 ("MEDIUM: haproxy-
|
|||
|
systemd-wrapper: Use haproxy in same directory"):
|
|||
|
|
|||
|
src/haproxy-systemd-wrapper.c: In function âlocate_haproxyâ:
|
|||
|
src/haproxy-systemd-wrapper.c:28:10: warning: ignoring return value of âreadlinkâ, declared with attribute warn_unused_result [-Wunused-result]
|
|||
|
|
|||
|
Fix the compiler warning by checking the return value of readlink().
