Copy characters in the specified range into an m-text.
MText* mtext_copy (MText * mt1, int pos, MText * mt2, int from, int to)
Copy characters in the specified range into an M-text. The mtext_copy() function copies the text between from (inclusive) and to (exclusive) in M-text mt2 to the region starting at pos in M-text mt1 while inheriting the text properties. The old text in mt1 is overwritten and the length of mt1 is extended if necessary. mt2 is not modified.
If the operation was successful, mtext_copy() returns a pointer to the modified mt1. Otherwise, it returns NULL and assigns an error code to the external variable merror_code.
