How to wrap a system call (libc function) in Linux · Saman Barghi
In order to wrap system calls in Linux, one have to wrap related glibc function calls. You have to be careful about the type of system calls you are tryting to override, since various functions might call different functions from glibc, e.g. printf calls puts from glibc which calls write at the end.

There are two ways to do this: 1-Using LD_PRELOAD environment variable, 2-using ld --wrap. I personally prefer the first approach since if the number of wrapper functions increases I do not have to specify them one by one, as in the second case.
