ssize_t rv was not decleared

[skeyvin]

#include "plthook.h"

ssize_t recv(){
ssize_t rv = main();
return rv;
};

int main(){
    plthook_t *hook;
    plthook_open(&hook, "vulkan.elf");
   recv();

};

i compile it with g++ main.cpp
and on the vulkan.elf i have everything in extern "C"{}
all plhook stuff is in the same directory as main.cpp
how do i solve this?
compiler error =

main.cpp: In function ‘ssize_t recv()’:
main.cpp:12:14: error: ‘main’ was not declared in this scope
   12 | ssize_t rv = main();
      |              ^~~~

The error itself is solved if int main(void); is added before ssize_t recv(){.
But even though it is solved, your code is useless. It calls main() and recv() alternately until the process crashes.
