xt_difftimeofday(3) Library Functions Manual xt_difftimeofday(3) NAME xt_difftimeofday() - Compute difference between struct timeval values LIBRARY #include <xtend/time.h> -lxtend SYNOPSIS time_t xt_difftimeofday(struct timeval *later, struct timeval *earlier) ARGUMENTS later, earlier: timeval structures populated by gettimeofday(3) DESCRIPTION xt_difftimeofday() returns the difference, in microseconds, between two time values returned by gettimeofday(3). This function can be used to get a good estimate of the real time elapsed in a process between any two points (where calls to gettimeofday(3) are strategically placed.) Use of these functions should have minimal impact on run time, unless called many times to measure time of a function with a very short run time. RETURN VALUES The difference between the two times in microseconds SEE ALSO gettimeofday(2), xt_tic(3), xt_toc(3) xt_difftimeofday(3)
