Functions


__EXPORT timeval microtimeout2Timeval (microtimeout_t to)
Convert a time interval, expressed as a microtimeout_t (number of microseconds), into a timeval value. microtimeout_t timeval2microtimeout (const timeval &t)
Convert a time interval, expressed as a timeval value into a microseconds counter. microtimeout_t timevalDiff2microtimeout (const timeval &t1, const timeval &t2)

Function Documentation

__EXPORT timeval microtimeout2Timeval (microtimeout_t to)

Convert a time interval, expressed as a microtimeout_t (number of microseconds), into a timeval value.

Parameters

to time interval, in microseconds.

Returns

the same time interval, as a timeval value.

microtimeout_t timeval2microtimeout (const timeval & t) [inline]

Convert a time interval, expressed as a timeval value into a microseconds counter.

Parameters

t time, as a timeval.

Returns

the same time, as a microseconds counter.

microtimeout_t timevalDiff2microtimeout (const timeval & t1, const timeval & t2) [inline]

Convert a time interval, expressed as the difference between two timeval values (t1-t2), into a microseconds counter.

Parameters

t1 First timeval.
t2 Second timeval.

Returns

difference between t1 and t2, in microseconds.
