Detailed Description

Time utilities.

Function Documentation

NsecToSec()

constexpr double fpsdk::common::time::NsecToSec ( const uint64_t ns )

staticconstexpr

Convert seconds to nanoseconds.

Note

Depending on the ns value this can be lossy.

Parameters

[in]

ns

Nanoseconds alue

Returns

the seconds value

Definition at line 67 of file time.hpp.

SecToNsec()

constexpr uint64_t fpsdk::common::time::SecToNsec ( const double sec )

staticconstexpr

Convert nanoseconds to seconds.

Parameters

[in]

sec

Seconds value

Returns

the nanoseconds value

Definition at line 79 of file time.hpp.

GetMillis()

uint64_t fpsdk::common::time::GetMillis

(

)

Get milliseconds [ms].

Time is monotonic time since first call to GetMillis() or GetSecs().

Returns

the number of milliseconds (> 0)

GetSecs()

double fpsdk::common::time::GetSecs

(

)

Get seconds [s].

Time is monotonic time since first call to GetMillis() or GetSecs().

Returns

the number of seconds
