XS: The equivalent of perl's ...

BrowserUk has asked for the wisdom of the Perl Monks concerning the following question:

keys %h = 12345;?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.

"The following functions have been flagged as part of the public API, but are currently undocumented. Use them at your own risk, as the interfaces are subject to change." I don't see a problem here, though. BrowserUk could always submit the appropriate documentation.	[reply]

From `mg.c`, the following is the code called after the the value is assigned to the scalar returned by `keys %h`, `sv` being that scalar, and `MUTABLE_HV(LvTARG(sv))` being the hash: `Perl_magic_setnkeys(pTHX_ SV sv, MAGIC mg) { PERL_ARGS_ASSERT_MAGIC_SETNKEYS; PERL_UNUSED_ARG(mg); if (LvTARG(sv)) { hv_ksplit(MUTABLE_HV(LvTARG(sv)), SvIV(sv)); } return 0; }` [download]	[reply] [d/l] [select]
