nofiles(descriptors) 1024
This means that I can open up to 1024 file per process? But wonder if there is any hardlimit imposed by Solaris 2.6 (eg 255) ?
By the way, is there any tool that can trace which files (or sockets) are opened by a process?
Thanks

sem_unlink
SEM_UNLINK(2) BSD System Calls Manual SEM_UNLINK(2)
NAME
sem_unlink -- remove a named semaphore
SYNOPSIS
#include <semaphore.h>
int
sem_unlink(const char *name);
DESCRIPTION
The named semaphore named name is removed. If the semaphore is in use by other processes, then name is immediately disassociated with the
semaphore, but the semaphore itself will not be removed until all references to it have been closed. Subsequent calls to sem_open() using
name will refer to or create a new semaphore named name.
If successful, sem_unlink() will return 0. Otherwise, -1 is returned and errno is set, and the state of the semaphore is unchanged.
ERRORS
sem_unlink() succeeds unless:
[EACCES] Permission is denied to be remove the semaphore.
[ENAMETOOLONG] name exceeded PSEMNAMLEN characters.
[ENOENT] The named semaphore does not exist.
SEE ALSO
sem_close(2), sem_open(2), semctl(2), semget(2), semop(2)
HISTORY
sem_unlink() is specified in the POSIX Realtime Extension (1003.1b-1993/1003.1i-1995).
