Question

I want to store some value from SQLite database in my buffer, but the qlite3_column_text() has the following prototype:

const unsigned char *sqlite3_column_text(sqlite3_stmt*, int iCol);

then when I do:

out[size] = sqlite3_column_text(stmt, 0);

I get the following error message:

assignment discards qualifiers from pointer target type

I tried using strcpy() too, but I get same error message.

Answer 1

It’s easy with strdup;

out[size] = strdup((const char*)sqlite3_column_text(stmt, 0));

Note that this will malloc the copy, so you have to call free() on the pointer later not to get a leak.

Of course this assumes that your out array can store values of the type char*, you’re not showing how it’s defined.
