Trngcc

Random number generation made easy in C

Source code

All of the sources you will need can be found in
the include folder

Why Trngcc?

• Easy
• Small
• Simple
• Works on any compiler
• Works on any standard
• Works on both C and C++
• No 3rd party dependencies
• GPLv3 (open source) license
• ...

Example

You can find multiple examples in tests folder,
but here's one:

#include "include/trngcc.h"
#include <stdio.h>

#define PASSES 1024

int main(void) {
    TrngccResult trng = trngcc("/dev/urandom");
    char buf[PASSES]  = {0};

    unsigned long idx;
    for (idx = 0; idx < 10000; ++idx)
        printf("%ld\n", trngcc_unranged(trng, PASSES, buf).res.i64);

    trngcc_end(trng);

    return 0;
}

This will print 10 thousand numbers, 1024 passes per
number

Testing

Just run the test.sh script, make sure you have gcc, g++, clang, clang++
and tcc installed, those compilers are the ones being tested, please install the
latest versions :)
