gettime 实用程序是一种 C 程序, PROBE 程序用此 C 程序跟踪两次重新启动该探测程序的操作之间的时间间隔。您必须编译此程序并将其放置在与回调方法相同的目录中,即,由 RT_basedir 特性指定此目录。
# # This utility program, used by the probe method of the data service, tracks # the elapsed time in seconds from a known reference point (epoch point). It # must be compiled and placed in the same directory as the data service callback # methods (RT_basedir). #pragma ident “@(#)gettime.c 1.1 00/05/24 SMI” #include <stdio.h> #include <sys/types.h> #include <time.h> main() { printf(“%d\n”, time(0)); exit(0); } |
