Usage

#include <ec.h>

int main(void) {
    if(ec_init() != 0) {
        //init failed
    }
    ...
}

ec.h is the only header required, and declares all user-accessible functionality. -lec will link to it.

ec_init() should be called before any other function in the library.

All functions other than ec_init() are thread-safe, but data structures should not be shared by multiple threads without appropriate protection.
