Function mynewt::kernel::os::os_mbuf_cmpf

pub unsafe extern "C" fn os_mbuf_cmpf(
    om: *const os_mbuf, 
    off: c_int, 
    data: *const c_void, 
    len: c_int
) -> c_int

Performs a memory compare of the specified region of an mbuf chain against a flat buffer.

• om: The start of the mbuf chain to compare.
• off: The offset within the mbuf chain to start the comparison.
• data: The flat buffer to compare.
• len: The length of the flat buffer.

Return: 0 if both memory regions are identical; A memcmp return code if there is a mismatch; INT_MAX if the mbuf is too short.
