Prefer to always declare and initialize variables to their closest first use

[ASmoliak]

In order to improve code density, it is widely accepted to initialize variables in the very first use, you can see in line 16 that you can just declare and initialize char *sockPath = argv[1]
and you can declare the struct in the line just before line 19.

Also, in C++ there is no need to specify 'struct' when declaring structs
