With clib

$ clib install jwerle/throw.h

usage

#include "throw.h"

int
main (void) {
  error_t eperm = error_new(EPERM, "EPERM");
  error_t enoent = error_new(ENOENT, "ENOENT");
  error_t esrch = error_new(ESRCH, "ESRCH");
  error_t eintr = error_new(EINTR, "EINTR");

  throw(&eperm, "Operation not permitted");
  throw(&enoent, "No such file or directory");
  throw(&esrch, "No such process");

You can also set the stream where errors are written to by defining the THROW_FD file descriptor.

THROW_FD = stderr; // or some other `FILE *` pointer
