The demo code:
typedef struct spmembuffer_t {
char * data;
int used;
int total;
} spmembuffer_t;
typedef struct spmemvfs_db_t {
sqlite3 * handle;
spmembuffer_t * mem;
} spmemvfs_db_t;
void test( spmemvfs_db_t * db )
{
......
// do whatever you want
errcode = sqlite3_exec( db->handle, ...... );
......
}
int readFile( const char * path, spmembuffer_t * mem )
{
// read file content from path
}
int writeFile( const char * path, spmembuffer_t * mem )
{
// write buffer into file
}
int main( int argc, char * argv[] )
{
const char * path = "abc.db";
spmemvfs_db_t db;
spmembuffer_t * mem = (spmembuffer_t*)calloc( sizeof(
spmembuffer_t ), 1 );
spmemvfs_env_init();
readFile( path, mem );
spmemvfs_open_db( &db, path, mem );
assert( db.mem == mem );
test( &db );
writeFile( path, db.mem );
spmemvfs_close_db( &db );
spmemvfs_env_fini();
return 0;
}
