END SUBROUTINE h5gget_comment_f
IN: Identifier of the file, group, dataset, or named datatype
const char *name
IN: Name of the object in loc_id whose comment is to be retrieved name must be '.' (dot) if loc_id fully specifies the object for which the associated comment is to be retrieved
IN: Anticipated required size of the comment buffer
OUT: The comment
H5G_GET_COMMENT retrieves the comment for the the object specified by loc_id and name. The comment is returned in the buffer comment.
loc_id can specify any object in the file. name can be one of the following: — The name of the object relative to loc_id — An absolute name of the object, starting from /, the file’s root group — A dot (.), if loc_id fully specifies the object
At most bufsize characters, including a null terminator, are returned in comment. The returned value is not null terminated if the comment is longer than the supplied buffer. If the size of the comment is unknown, a preliminary H5G_GET_COMMENT call will return the size of the comment, including space for the null terminator.
If an object does not have a comment, the empty string is returned in comment.
Returns the number of characters in the comment, counting the null terminator, if successful; the value returned may be larger than bufsize. Otherwise returns a negative value.
