From 423e49023eeb9b93dcf335d7b03e86a44e584dc8 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 10 May 2019 07:23:53 -0700 Subject: preadv/pwritev: fix offset argument type preadv/pwritev don't provide separate version for 64-bit wide off_t, and default to 32-bit wide off_t, which results in a mismatch between declaration and definition for user programs built with -D_FILE_OFFSET_BITS=64. Make offset argument of both functions __off64_t. This fixes test misc/tst-preadvwritev on xtensa.
