Functions wrapped in .Call() are implemented in a compiled language,
with corresponding sources in the src/ directory of a package.

For example, the call to C_R_igraph_shortest_paths seems to end up in
https://github.com/igraph/igraph/blob/6faf5610b8ab0175466e93a8a1d1981987976a38/src/structural_properties.c#L460
