I believe the extra characters type-encode the function and provide it
a signature (for the linker's benefit).  See section 7.2.1c (p. 122)
of the Annotated C++ Reference Manual by Ellis and Stroustrup.

My initial parse of FiPFve_v is: F - global function, i - 1st arg
"int", P - pointer, F - function, v - "void", e - "...", _v - dunno.
I'm sure someone else can interpret this more intelligently.
