svn_error_t* svn_hash__clear	(	apr_hash_t *	hash,
		apr_pool_t *	pool
	)

Clear any key/value pairs in the hash table.

A wrapper for a apr_hash_clear(), which isn't available until APR 1.3.0.

Since:

New in 1.5.

svn_error_t* svn_hash_from_cstring_keys	(	apr_hash_t **	hash,
		const apr_array_header_t *	keys,
		apr_pool_t *	pool
	)

Set *hash to a new hash whose keys come from the items in keys (an array of const char * items), and whose values are match their corresponding key.

Use pool for all allocations (including *hash, its keys, and its values).

Since:

New in 1.5.

svn_error_t* svn_hash_keys	(	apr_array_header_t **	array,
		apr_hash_t *	hash,
		apr_pool_t *	pool
	)

Return the keys to hash in *array.

The keys are assumed to be (const char *). The keys are in no particular order.

*array itself is allocated in pool; however, the keys are not copied from the hash.

Since:

New in 1.5.
