clockid_t
CLOCK_*
constants for use with clock_gettime_dynamic
.
These constants may be unsupported at runtime, depending on the OS version,
and clock_gettime_dynamic
may fail with INVAL
. See ClockId
for
clocks which are always supported at runtime.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
