 * Function:	H5T_enum_nameof
 *
 * Purpose:	Finds the symbol name that corresponds the the specified
 *		VALUE of an enumeration data type DT. At most SIZE characters
 *		of the symbol name are copied into the NAME buffer. If the
 *		entire symbol name and null terminator do not fit in the NAME
 *		buffer then as many characters as possible are copied and the
 *		function returns failure.
 *
 *		If NAME is the null pointer and SIZE is zero then enough
 *		space is allocated to hold the result and a pointer to that
 *		memory is returned.
 *
 * Return:	Success:	Pointer to NAME
 *
 *		Failure:	NULL, name[0] is set to null.
