Get the topmost text property.
MTextProperty* mtext_get_property (MText * mt, int pos, MSymbol key)
Get the topmost text property. The mtext_get_property() function searches the character at position pos in M-text mt for a text property whose key is key.
If a text property is found, mtext_get_property() returns it. If there are multiple text properties, it returns the topmost one. If no such property is found, it returns NULL without changing the external variable merror_code.
If an error is detected, mtext_get_property() returns NULL and assigns an error code to the external variable merror_code.
