             Bug #: 15137
           Summary: linking static version of sem_open gets message
                    "'mktemp' is dangerous, better use `mkstemp'"
           Product: glibc
           Version: 2.11
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: unassigned@sourceware.org
        ReportedBy: geir@cray.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


In the following test case that calls sem_open, a link time warning message is
produced when linked statically.  sem_open needs to be changed so that this
link time message no longer appears, as it is unacceptable that the use of a
supported system library routine produces this type of link time warning.

$ cat sem_open.c
#include <fcntl.h>
#include <semaphore.h>
#include <errno.h>

int main(int argc, char *argv[])
{
  sem_t *mutex;

  /* create, initialize semaphore */
  if ((mutex = sem_open("mysemaphore", O_CREAT, 0644, 1)) == SEM_FAILED)
      perror("semaphore initilization");

  return 0;
}

$ gcc -static sem_open.c -lpthread
/usr/lib/../lib64/libpthread.a(sem_open.o): In function `sem_open':
/usr/src/packages/BUILD/glibc-2.11.3/nptl/sem_open.c:333: warning: the use of
`mktemp' is dangerous, better use `mkstemp'
$ gcc sem_open.c -lpthread
