XmTabListInsertTabs creates a new tab list that includes the tabs in oldlist. This function copies
specified tabs to the tab list at the given position. The first tab_count tabs of the tabs array are
added to the tab list. If oldlist is NULL, XmTabListInsertTabs creates a new tab list containing only the
tabs specified.
oldlist Specifies the tab list to add the tabs to. The function deallocates oldlist after extracting
the required information.
tabs Specifies a pointer to the tabs to be added to the tab list. It is the caller's responsibility
to free the tabs in tabs by using XmTabFree.
tab_count Specifies the number of tabs in tabs.
position Specifies the position of the first new tab in the tab list. A value of 0 (zero) makes the
first new tab the first tab in the tab list, a value of 1 makes it the second tab, and so on.
If position is greater than the number of tabs in oldlist, then the tabs will be inserted at
the end. If position is negative, the count will be backwards from the end. A value of -1 makes
the first new tab the last tab, and so on.
