NAME

       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.
