xRingbufferGetMaxItemSize() function
Get maximum size of an item that can be placed in the ring buffer This function returns the maximum size an item can have if it was placed in an empty ring buffer.
Syntax
Implemented in ![]()
ringbuf.c:1257
Return value
Maximum size, in bytes, of an item that can be placed in a ring buffer.
Notes
The max item size for a no-split buffer is limited to ((buffer_size/2)-header_size). This limit is imposed so that an item of max item size can always be sent to an empty no-split buffer regardless of the internal positions of the buffer's read/write/free pointers.
