XmStringCreateLtoR creates a compound
string with two components: text and a font list element tag.
This function imposes the semantic of scanning for \n
characters in the text. When one is found, the text up to that point
is put into a segment followed by a separator component. No final
separator component is appended to the end of the compound string.
The direction defaults to left-to-right.
This function assumes that the encoding is single octet
rather than double octet per character of text.
text
Specifies a null-terminated string to be used as the text component of
the compound string.
tag
Specifies the font list element tag to be associated with the given
text. The value XmFONTLIST_DEFAULT_TAG identifies a locale
text segment.
