New Revision: 1272
Log:
Tentative fix for warnings about unused return values in arp.c
arp.c: In function ‘pisa_arp_cache_update’:
arp.c:117: warning: ignoring return value of ‘fgets’, declared with attribute
warn_unused_result
arp.c:120: warning: ignoring return value of ‘fgets’, declared with attribute
warn_unused_result
As I can't reproduce the warnings, the fix is labeled as tentative.
