From ec721f3305c04b5d136e2d21cb73c5bdfdd81684 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 16 Jun 2016 23:53:47 +0200 Subject: py_getrandom(): use long type for the syscall() result Issue #27278. It should fix a conversion warning. In practice, the Linux kernel doesn't return more than 32 MB per call to the getrandom() syscall. --- Python/random.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Python/random.c b/Python/random.c index 8ce0b3e..3119872 100644 --- a/Python/random.c +++ b/Python/random.c @@ -132,7 +132,7 @@ py_getrandom(void *buffer, Py_ssize_t size, int raise) * see https://bugs.python.org/issue26839.
