Re: stop mount/read/write

[Vishal Thanki <vishalthanki@xxxxxxxxx>]

In case where you want to intercept these calls, you can write a shared 
library by having your implementation of these calls (i.e. 
read/write/mount). And then, set the path of this library in LD_PRELOAD 
environment. Any application running under this environment variable 
set, will invoke your implementation instead of calling system call.

Vishal
