HI
I use sqlite3 on embedded arm
my memory is very small free memory about 6M
so i want to use MEMSYS5 to limit memory use
i define DSQLITE_ENABLE_MEMSYS5=1 in sqlite3.c
compile it
in my code start i use
sqlite3_config(SQLITE_CONFIG_HEAP,malloc(2*1024*1024),2*1024*1024);
sqlite3_config(SQLITE_CONFIG_PAGECACHE,malloc(4*1024),4*1024);
before open database
my purpose is to limit memory usage < 2M + 4K
but i found sqlite3_memory_used=29126656
is use 27M?? i can"t understand why
what sqlite3_memory_used mean ?
if i want to limit memory about 4M ? what i should config the sqlite3?
