Use sysconf to determine the maximum number of standardI/O streams a process can open at a time. Then try to open this number of streams. How many can you open? Does it match whatsysconfreports?
What will be an ideal response?
The results differ depending on which platform you use. Solaris 10 reports STREAM_MAX to be 256, but we can open only 253 standardI/O streams. This is because our program already has 3 open streams when it starts: standard input, standardoutput, and standarderror.OnMac OS X 10.6.8, the behavior is similar to Solaris. FreeBSD 8.0 reports STREAM_MAX to be 20,000, but we can only open 15,098 standardI/O streams. In this case, we probably arerunning into the system-wide limit for open ?les. Linux 3.2.0 reports STREAM_MAX to be 16, but we can open 1021 streams. This means the limit is really 1024.
