From d61d0d3f6dbd960a761c05ff7fea848cb6490aa3 Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Sun, 23 Sep 2001 02:05:26 +0000 Subject: [PATCH] Added API information for the PyCallIter_*() and PySeqIter_*() functions. Added signatures for some new PyType_*() functions. --- Doc/api/api.tex | 60 ++++++++++++++++++++++++++++++++++++++++++- Doc/api/refcounts.dat | 7 +++++ 2 files changed, 66 insertions(+), 1 deletion(-) diff --git a/Doc/api/api.tex b/Doc/api/api.tex index 7b205cad888..a7270411cfc 100644 --- a/Doc/api/api.tex +++ b/Doc/api/api.tex @@ -2337,6 +2337,18 @@ Returns true if the type object \var{o} sets the feature \var{feature}.
