Hi,
thx for ur reply.
i wanted to know in side kernel is there any limit to
the malloc that a user can do.what you told in ur
previous mail is that at a time user can malloc 4k.but
suppose i am doing 2k memory allocations. how many
such mallocs i can do?
is there any configuration we can do depending on our
RAM size?
please reply.
thx
