Describes a segment of data
| Variables | |
| data | contains a reference to the actual data storage in an mos_buf_impl_t |
| next | Contains a reference to the next buffer part in the sequence |
| prev | Contains a reference to the previous buffer part in the sequence |
| size | amount of bytes referenced by this buffer part |
| offset | offset into the actual data that stores the data |
mos_buf_impl_t * data
contains a reference to the actual data storage in an mos_buf_impl_t
Contains the hidden portion of a buffer object. It is located directly in front of the udi_buf_t structure Buffers are composed of segments of immutable data, stored in a linked-list fashion. This gives O(1) access to the most expected operation (concatenations), but suffers on repeated random mutations. However, buffer calls should be minimal compared to the actual amount of data stored due to general overhead.
| Variables | |
| first | Contains a pointer to the first buffer part in the list, which is a mos_buf_part_t. |
