in reply to XS replacing my c library, not compatible with OS threads

Yep. The default behavior is great for core perl development but can be a major headache for green XS and embedding authors.

The 'secret' is to #define NO_XSLOCKS before including XSUB.h. If left undefined, XSUB.h will redefine a long list of functions/macros (including free, malloc, and exit) with internal versions.

[Your Mother]: "They" is becoming accepted but it irritates me sometimes. I tend to just pick she or he randomly or try to use "one."
LanX thinks it is appropriate here :)
[Your Mother]: They would think so.
[jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
[jdporter]: without using a tmp file
[1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
[jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
[1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
[LanX]: jdporter: open PIPE,'-|' ?
