Dear all,
in an upcoming project, it is required to store all integer values as little
endian
instead of big endian (don't ask why).
Nevertheless, I would like to use SQLite in that project.
What do we have to change in the sqlite library,
if we store the integers as little endian.
I came across

Does that mean you are not allowed to use TCP/IP which
stores everything big-endian? ;-)

I think there is no need to change endianess.
Sqlite is shadowing out this and similar low level aspects.
If you need to get data from database and use it in something what needs it in
other endianess, you may use something like this.
int change_endianess(unsigned char *data, int length)
{
I want to reserve a specific size for every database when it is
created.
Is that possible?
Thanks

This will only work if you do NOT enable auto-vacuum. To
repeat: auto-vacuum must be switched off.
When you create the database, create a table

Hi all,
I have searched the web, the newsgroups, and the archives, but all I can

of references that list this as predefined error #13

All:
I was wondering exactly how SQLite handles freeing memory used
from the heap when compiled without SQLITE_ENABLE_MEMORY_MANAGEMENT?
Will absolutely no memory be freed, or is there some default
memory management scheme used?
There is an important element to bear in mind when using mmaping to take
advanrage of physical memory. The POSIX advisory file locks are not
necessarily effective in that mode.
