pthread_create

[Jonny Grant <jg@jguk.org>]

Hello mtk,

https://www.man7.org/linux/man-pages/man3/pthread_create.3.html

This has a good example I saw, what do you think about replacing these pre-processor macros containing do {} while(0) with regular functions?

Something like this:

void handle_error_en(int en, const char * const msg)
{
      errno = en;
      perror(msg);
      exit(EXIT_FAILURE);
}

void handle_error(const char * const msg)
{
      perror(msg);
      exit(EXIT_FAILURE);
}


Although I don't think errno is such a good idea. so I'd probably write:

void handle_error_en(int en, const char * const msg)
{
      fprintf(stderr, "%s: %s\n", msg, strerror(en));
      exit(EXIT_FAILURE);
}

I'd also suggest adding the command line to compile $ cc -Wall -pthread -o threads threads.c
