STINNER Victor <vstin...@python.org> added the comment:
Attached set_unset_env.c program calls putenv("=hello world") and then
unsetenv("").
On my Fedora 34 with glibc-2.33-20.fc34.x86_64, putenv() succeed, but
unsetenv() fails.
---
$ gcc set_unset_env.c -g -o set_unset_env && ./set_unset_env
putenv("=hello world") -> hello world
ERROR: unsetenv("") failed: [error 22] Invalid argument
---
By the way, getenv() fails to find an environment variable if its name is
empty: I reimplemented getenv() using the 'environ' variable for my test.
