Hi guys,
I am developing an app, and at the state it is, i am looking now to
details...
I tried valgrind-3.8.1, on Debian amd_64.
struct record{
uint8_t data_size;
uint8_t rec_type;
uint16_t addr;
uint8_t *data;
uint8_t checksum;
};
struct holder{
uint32_t nrecords;
struct record *records;
};
struct holder blahhh = {0, NULL);
blahhh.records = ( struct record *) calloc( sizeof( struct record ),
holder.nrecords );
blahhh.records[ record_no ].data = calloc( record_len, 1 );//I alloc an
amount of record data chars
when i freed the mem i free everithyng
free(blahhh.records[ record_no ].data);
free(blahhh.records);
my problem is..
I run :
valgrind ./program
and I get lots of unitialized blocks :S
..
....
.....

==24106== total heap usage: 0 allocs, 0 frees, 0 bytes allocated
==24106==
==24106== All heap blocks were freed -- no leaks are possible
how can total heap be:
total heap usage: 0 allocs, 0 frees, 0 bytes allocated ???
even with "valgrind --tool=memcheck ./program"
i get the same :(
does any one knows how to track the mallocs and free ??
thanks in advance
regards,
tux
