How to get microseconds of system time from Redhat Linux 4.0..

Answer / rajeev kumar verma

The systemcall "gettimeofday" can be used to get the time in microseconds. The call takes two arguments.
1- struct timeval
2- struct timezone ( for timezone information). you can have second argument null.
timeval structure has two fields:
tv_sec ( represents time in seconds)
tv_usec ( represents time in microseconds )

the code snapshot is :
////
struct timeval t_time;
gettimeofday(&t_time,NULL);
