	)

Definition at line 134 of file spf_dns_rr.c.

SPF_errcode_t SPF_dns_rr_dup	(	SPF_dns_rr_t **	dstp,
		SPF_dns_rr_t *	src
	)

This function may return both an error code and an rr, or one, or neither.

This function generates a valgrind error because strlen always reads in blocks of 4 bytes, and can overrun the end of the allocated buffers.
