pub unsafe fn hash_copy(
    table: *mut HashTable,

) -> *mut HashTable

UPSTREAM-PARITY

xmlHashTablePtr xmlHashCopy(xmlHashTablePtr table, xmlHashCopier f);

Creates a new hash table with copied entries. The f function is called for each entry to create a copy of the payload.

Returns the new hash table, or NULL on failure.

SAFETY

• table must be a valid pointer to a HashTable, or NULL.
• f may be NULL (payloads are copied by pointer).
