socket() function from nacl sdk returns -1

Question

I have build chrome app with nacl module which calls socket() function, but the function returns -1. I have compiled the module with -lnacl_io linker option. Also I have tried to run Goolgle Chrome with --allow-nacl-socket-api=localhost. I call this function with the next arguments:

socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)

Why is this function failed?

Answer 1

Don't forget to call nacl_io_init_ppapi function
