I use the gcc compiler (Compiler flags: -DHPUX_THREADS -DINLINE_PRAGMA, linking: -ltermcap -lm -ldce). An example for the sem_init call:
#include <semaphore.h>
sema_t sema ;
assert(semap) ;
*semap = NULL ;
sema = (sema_t) malloc(sizeof(*sema)) ;
if (sema == NULL) return -1;
if (sem_init(&sema->sema, initial_value, 0)) {
switch(errno)
{
case EINVAL:
{
fprintf(stderr, " errno= EINVAL \n");
break;
}
case ENOSPC:
{
fprintf(stderr, " errno= ENOSPC \n");
break;
}
case ENOSYS:
{
fprintf(stderr, " errno= ENOSYS \n");
break;
}
case EPERM:
{
fprintf(stderr, " errno= EPERM \n");
break;
}
default:
{
fprintf(stderr, " errno= unbekanntes Problem \n");
break;
}
}
return -1;
}
*semap = sema ;
return TEST_OK;
}
The exception I get is ENOSYS (The sem_init function is not supported by the system). It looks that semaphore.h is not yet implemented.

Subject: [HPADM] Problems with semaphores under HP 10.20
Hello,
I've problems with semaphores under HP-UX 10.20. I've include the semaphore.h file and will be use the functions sem_init, sem_wait, sem_post, sem_destroy and sem_close. When I call one of the functions I get an exception ENOSYS (The ... function is not supported by the system). How can I resolve the problem? Does it give any patch or an update for HP-UX 10.20?
Best regards
Sascha
