When sending messages, there has to be an available message slot available (<code>max_messages!=message_count</code>), and there has to be enough space available (<code>msghdr_contentsize+0x10 + cur_size <= max_size</code>). After pushing the storage, message_count is incremented and cur_size is increased by <code>msghdr_contentsize+0x10</code>. | When sending messages, there has to be an available message slot available (<code>max_messages!=message_count</code>), and there has to be enough space available (<code>msghdr_contentsize+0x10 + cur_size <= max_size</code>).

* 0x0: Does some validation | * 0x0: Does some validation. Reads the message content into the user buffer, when contentsize is non-zero. The original contentsize is written to an user output param. The last byte in the user buffer (contentsize clamped to the user max-buf-size) is set to 0 for NUL-termination. | ||
