mbuf_setflags_mask

Declaration

errno_t mbuf_setflags_mask(mbuf_t mbuf, mbuf_flags_t flags, mbuf_flags_t mask);

Parameters

• mbuf:

  The mbuf.

• flags:

  The flags that should be set or cleared. Certain flags such as MBUF_EXT cannot be altered.

• mask:

  The mask controlling which flags will be modified.

Return Value

0 upon success otherwise the errno error.

Discussion

Useful for setting or clearing individual flags. Easier than calling mbuf_setflags(m, mbuf_flags(m) | M_FLAG).
