dtk_difftime_s, dtk_difftime_ms, dtk_difftime_us, dtk_difftime_ns - timestamp difference SYNOPSIS
#include <dtk_time.h> long dtk_difftime_s(const struct dtk_timespec* ts, const struct dtk_timespec* orig); long dtk_difftime_ms(const struct dtk_timespec* ts, const struct dtk_timespec* orig); long dtk_difftime_us(const struct dtk_timespec* ts, const struct dtk_timespec* orig); long dtk_difftime_ns(const struct dtk_timespec* ts, const struct dtk_timespec* orig); DESCRIPTION
These functions returns the difference of time from orig to ts. dtk_difftime_s() returns the difference in seconds. dtk_difftime_ms() returns the difference in milliseconds. dtk_difftime_us() returns the difference in microseconds. dtk_difftime_ns() returns the difference in nanoseconds. RETURN VALUE
All the functions return the difference of time. SEE ALSO

Detailed Description Todo description Function Documentation struct timeval tevent_timeval_add (const struct timeval *tv, uint32_tsecs, uint32_tusecs) Add the given amount of time to a timeval structure. Parameters: tv The timeval structure to add the time. secs The seconds to add to the timeval. usecs The microseconds to add to the timeval. Returns: The timeval structure with the new time. int tevent_timeval_compare (const struct timeval *tv1, const struct timeval *tv2) Compare two timeval values. Parameters: tv1 The first timeval value to compare. tv2 The second timeval value to compare. Returns: 0 if they are equal. 1 if the first time is greater than the second. -1 if the first time is smaller than the second. Compare two timeval values. Return -1 if tv1 < tv2 Return 0 if tv1 == tv2 Return 1 if tv1 > tv2 struct timeval tevent_timeval_current (void) Get a timeval value for the current time. Returns: A timval value with the current time. Get a timeval value for the current time. struct timeval tevent_timeval_current_ofs (uint32_tsecs, uint32_tusecs) Get a timeval in the future with a specified offset from now. Parameters: secs The seconds of the offset from now. usecs The microseconds of the offset from now. Returns: A timval with the given offset in the future. Get a timeval in the future with a specified offset from now. bool tevent_timeval_is_zero (const struct timeval *tv) Check if a given timeval structure is zero. Parameters: tv The timeval to check if it is zero. Returns: True if it is zero, false otherwise. Check if a given timeval structure is zero. struct timeval tevent_timeval_set (uint32_tsecs, uint32_tusecs) Get a timeval structure with the given values. Parameters: secs The seconds to set. usecs The microseconds to set. Returns: A timeval structure with the given values. Get a timeval structure with the given values. struct timeval tevent_timeval_until (const struct timeval *tv1, const struct timeval *tv2) Get the difference between two timeval values. Parameters: tv1 The first timeval. tv2 The second timeval. Returns: A timeval structure with the difference between the first and the second value. Get the difference between two timeval values. struct timeval tevent_timeval_zero (void) Get a zero timval value. Returns: A zero timval value. Get a zero timval value.
