C++ (Cpp) inc_fd_ref_count Beispiele

Beispiel #1

Datei: fd.cpp Projekt: looncraz/haiku

struct file_descriptor *
get_fd(struct io_context *context, int fd)
{
	struct file_descriptor *descriptor = NULL;

	if (fd < 0)
		return NULL;

	fssh_mutex_lock(&context->io_mutex);

	if ((uint32_t)fd < context->table_size)
		descriptor = context->fds[fd];

		if (descriptor->open_mode & FSSH_O_DISCONNECTED)
			descriptor = NULL;
		else
			inc_fd_ref_count(descriptor);
	}

	fssh_mutex_unlock(&context->io_mutex);

	return descriptor;
}

	if (descriptor != NULL) {

		inc_fd_ref_count(descriptor);
	}

	return descriptor;
}
