Function svn_hash_from_cstring_keys 

pub unsafe extern "C" fn svn_hash_from_cstring_keys(
    hash: *mut *mut apr_hash_t,
    keys: *const apr_array_header_t,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Set @a *hash to a new hash whose keys come from the items in @a keys (an array of const char * items), and whose values are match their corresponding key. Use @a pool for all allocations (including @a *hash, its keys, and its values).
