Subject: [PATCH] Use C99 format macro constants for timestamp and vlan_tag
|
|
|
|
Since timestamp and vlan_tag in the shm_log_entry struct are C99 fixed
|
|
width integer types (uint64_t and uint16_t), the cross-platform way to
|
|
print these values is to use the corresponding format macro
|
|
constants[1], PRIu64 and PRIu16.
|
|
|
|
This also adjusts the places where the time_t timestamp value is
|
|
printed, casting it to uint64_t, for consistency.
|
|
|
