       Get the value of the topmost text property. The mtext_get_prop() function searches the character at pos
       in M-text mt for the text property whose key is key.

           MERROR_RANGE, MERROR_SYMBOL

           If a text property is found, mtext_get_prop() returns the value of the property. If the property has
           multiple values, 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_prop() returns NULL and assigns an error code to the external variable
       merror_code.

       Note

           If NULL is returned without an error, there are two possibilities:

       • the character at pos does not have a property whose key is key, or
       • the character does have such a property and its value is NULL.

       If you need to distinguish these two cases, use the mtext_get_prop_values() function instead.

           mtext_pop_prop(), mtext_prop_range()
