Question

I’m trying to pass my sqlite database through to a function and then through to another one again. Here is my code.

//database Name
// Create a handle for database connection, create a pointer to sqlite3
sqlite3 *dataDB;

//I send it through to the function here
// Execute the query for creating table
retval = sqlite3_exec(dataDB,create_students,0,0,0);

My prototypes:

int readInFiles(sqlite3 ** dataDB);
void addCourse(sqlite3 ** dataDB, struct course,int k);

Call from within the readInFiles function:

addCourse(&dataDB,deg,k);

Here is my error:

"database.c", line 50: warning: argument #1 is incompatible with prototype:
      prototype: pointer to pointer to struct sqlite3 {} : "database.h", line 51

Answer 1

From within readInFiles, dataDB is of type sqlite3** already, so you need to call:

addCourse(dataDB,deg,k);
