Subject: [PATCH libibverbs] memory: use SCNxPTR format to read uintptr_t values
Date: Wed, 11 Jul 2012 17:10:35 +0200	[thread overview]
Message-ID: <1342019435-10041-1-git-send-email-ydroneaud@opteya.com> (raw)

SCNxPTR is the correct format to parse uintptr_t hexadecimal values,
whatever the width of uintptr_t type.

This fix a warning when building on a 32bits system.
