Making addresses from the address specified and given size in the child's address space and make it valid.

[kota saikrishna]

Hello,

I am trying to inject code into the child process using ptrace utility.
The function of the injecting code is to make addresses from the address
specified and the size in the child's address space and make it valid(i.e
to read and write ..).
On my knowledge i tried to use mmap system call but i could not able to
allocate the memory can any one help in this point how to achieve this.
