sem_print(3C)

NAME
     sem_print - print the state of a POSIX semaphore

C SYNOPSIS
     #include <semaphore.h>
     int sem_print (sem_t *sem, FILE *fd, const char *label);

DESCRIPTION
     sem_print obtains all the semaphore state of sem and writes it as a
     formatted string to fd.  The string is prefixed with a user specified
     label.

     Semaphore types other than shared POSIX unnamed semaphores are not
     supported by this function.

     sem_print is an IRIX extension to the POSIX interfaces and is not part of
     the IEEE 1003.1b Standard.

     sem_print will fail if one or more of the following are true:

     [EINVAL]       The specified semaphore is not a supported semaphore type.

     [EBADF]        The specified file is invalid.

DIAGNOSTICS
     Upon successful completion, a value of 0 is returned to the calling
     process. Otherwise, a value of -1 is returned and errno is set to
     indicate the error.
