Reference 1003.1, 2004 edition p1306 l40983
If the envname argument points to a string containing an "=" character
then setenv() shall fail and set errno to EINVAL.
The following code checks that an environment variable "ENVVAR" is not
set and then calls setenv() with the envname argument "ENVVAR="
and the envval argument to to "VALUE2", it should fail returning
-1 and setting EINVAL but succeeds and sets the environment
variable to the value "=VALUE2"
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
main()
{
int ret;
int err;
errno=0;
/* get the value */
printf ("Check that ENVVAR is not set in the environment\n");
printf ("ENVVAR expected \"(null)\" got \"%s\"\n", getenv("ENVVAR"));
/* set an environment name containing an = character */
printf ("call setenv() with envname set to \"ENVVAR=\" and envval set to
\"VALUE2\"\n");
errno=0;
ret=setenv("ENVVAR=", "VALUE2", 1);
/* should fail*/
err=errno;
if (ret != -1)
{
printf("setenv FAIL:expected to fail since envname contain an =
character\n");
printf("errno=%d, expected EINVAL\n", err);
}
printf ("ENVVAR expected \"(null)\" got \"%s\"\n", getenv("ENVVAR"));
}
$ make CC=c99 CFLAGS=-D_POSIX_C_SOURCE=200112L setenv
make: `setenv' is up to date.
-sh-2.05b$ ./setenv
Check that ENVVAR is not set in the environment
ENVVAR expected "(null)" got "(null)"
call setenv() with envname set to "ENVVAR=" and envval set to "VALUE2"
setenv FAIL:expected to fail since envname contain an = character
errno=0, expected EINVAL
ENVVAR expected "(null)" got "=VALUE2"

------- Additional Comments From a dot josey at opengroup dot org 2004-07-23 13:28 -------
Similarly calling setenv() with an envname set to an empty string succeeds when
it is expected to fail (return -1 and set errno to EINVAL)
setenv("", "value", 0);
setenv("", "value", 1)
When called with the first argument a null pointer, it should also fail, but
instead segment faults.

glibc 2.3.2 is way too old.
This has been fixed in CVS 1.5 months ago.
