Find the key of a dictionary entry (returns a string)
#include <strm.h> const char *strm_dict_key_get( const strm_dict_t *dict, size_t n );
libstrm
The function strm_dict_key_get() finds the key of the (n+1)th entry in the specified dictionary and returns it as a null-terminated string. For example, if n is 3, the key of the fourth entry is returned. The returned string is owned by the dictionary object, and remains valid until the dictionary handle is destroyed.
The specified key on success, or a null pointer on failure.
