GSL functions are regular C-functions and should be used as such.
In your particular example, please, see GSL documentation, section 32
"One dimensional Root-Finding", subsection 32.10 "Examples" on how to
pass functions as arguments to root solvers. By the way,
implementation of your function could contain integrals, etc.
