46 * @eseq: errseq_t field that should be set
49 * This function sets the error in @eseq, and increments the sequence counter

112 * @eseq: Pointer to errseq_t to be sampled.

135 * @eseq: Pointer to errseq_t value to be checked.

156 * @eseq: Pointer to value being checked and reported.
159 * Grab the eseq value, and see whether it matches the value that @since
163 * swap it into place as the new eseq value. Then, set that value as the new
