A library for wrapping function calls to shared libraries
Description
Gotcha is a library that wraps functions. Tools can use gotcha to install hooks
into other libraries, for example putting a wrapper function around libc's
malloc. It is similar to LD_PRELOAD, but operates via a programmable API. This
enables easy methods of accomplishing tasks like code instrumentation or
wholesale replacement of mechanisms in programs without disrupting their source
code.
