We can implement something _similar_ to getprogname. But it won't be
the same API, because
- our function can return NULL,
- our function can return a truncated value,

Given the results of your (impressive) research, I'm tempted to
go with this approach.
A fallback position might be to implement only A (the sh
Hi,
How can some library code determine the name of the running program,
for error message and display purposes, if the program's main() function
has not stored argv[0] in a particular place?
