🚀 go-pugleaf

(My apologies if this one is already well known)

The following program demomstrates a bug on SunOS 4.1.2.  The
initgroups() library call fails to set the groups properly when a
program calling it is made with /usr/5bin/cc.  It works okay when
compiled with /bin/cc.

My guess to the cause of the problem has to do with the arugument
types passed to getgroups() from within initgroups().  The SystemV
synopsis calls for arguments of type gid_t (unsigned short); otherwise
the args would be ints.


#include <stdio.h>
#include <sys/types.h>
#include <pwd.h>

main()
{
	struct	passwd *pwd, *getpwnam();

	if((pwd = getpwnam("j4jbail")) == NULL) {
		printf("getpwnam() failed\n");
		exit(1);
	}

	system("id");

	if(initgroups(pwd->pw_name, pwd->pw_gid) < 0) {
		printf("initgroups() failed\n");
		exit(1);
	}

	system("id");

	exit(0);
}
