insertion with hint

The C++ standard (ISO/IEC 14882:2003) states in table 69 (in clause
23.1.2), for the insert member with a hint:
"Complexity: logarithmic in general, but amortized constant if t is
inserted right after p."

t is the inserted object and p the hint.

If this is the case, how would I give a hint to insert t to the
beginning of an associative container ?
