- Subject: Hook functions for system calls
I want to write hook functions for system calls that happen either
directly or indirectly ie. I need my hook write function to be invoked
whenever write() or fprintf() system call is invoked by the program. I
tried tweaking glibc but not able to find exact point when I can plugin
the hook function. Any suggestions?
