Name: H5Aget_name
Signature:
ssize_t H5Aget_name(hid_t attr_id, size_t buf_size, char *buf )
Purpose:
Gets an attribute name.
Description:
H5Aget_name retrieves the name of an attribute specified by the identifier, attr_id. Up to buf_size characters are stored in buf followed by a \0 string terminator. If the name of the attribute is longer than (buf_size -1), the string terminator is stored in the last position of the buffer to properly terminate the string.

If the user only wants to find out the size of this name, the values 0 and NULL can be passed in for the parameters bufsize and buf.

Parameters:
Returns:
Returns the length of the attribute's name, which may be longer than buf_size, if successful. Otherwise returns a negative value.
