X-Git-Tag: v4.15~135
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=35126cda20ed9c1077aa5a70e68301821b616fd1;p=strace

tests: fix "comparison between signed and unsigned" compilation warnings

preadv-pwritev.c: In function 'main':
preadv-pwritev.c:162: warning: comparison between signed and unsigned
readv.c: In function 'main':
readv.c:148: warning: comparison between signed and unsigned
recvmsg.c: In function 'main':
recvmsg.c:148: warning: comparison between signed and unsigned

* tests/preadv-pwritev.c (main): Cast r_len to int.
* tests/readv.c (main): Likewise.
* tests/recvmsg.c (main): Likewise.
