Hi,
Sorry that i have been unable to clarify my question, I here am asking question
why the commands fopen(write mode) and open(O_CREAT) take 15-20 milliseconds
and 5-10 milliseconds respectively on Solaris whereas they take 0 milliseconds
on other OSes.
Basically the output of the below prog on other OSes is faster:
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <fcntl.h>
#include <errno.h>
int main()
{
hrtime_t t1, t2;
unsigned long timeTaken;
FILE * fp;
int fd;
t1 = gethrtime();
fp = fopen("abcd.txt","w");
t2 = gethrtime();
if (fp == NULL)
printf("fopen() failed, errno = %d\n", errno);
timeTaken = (long)(t2 - t1);
printf("time taken %ld\n",timeTaken);
t1 = gethrtime();
fd = open("abcd.txt", O_CREAT);
t2 = gethrtime();
if (fd < 0)
printf("open() failed, errno = %d\n", errno);
timeTaken = (long)(t2 - t1);
printf("time taken %ld\n",timeTaken);
return 1;
}
Regards,
Gaurav
