       Get multiple text properties. The mtext_get_properties() function searches the character at pos in M-text
       mt for properties whose key is key. If such properties are found, they are stored in the memory area
       pointed to by props.  num limits the maximum number of stored properties.

           If the operation was successful, mtext_get_properties() returns the number of actually stored
           properties. If the character at pos does not have a property whose key is key, the return value is 0.
           If an error is detected, mtext_get_properties() returns -1 and assigns an error code to the external
           variable merror_code.
