Subject: vss.c: Don't try to mmap empty files
X-Git-Tag: v0.2.16~13
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=e7788710ef8d47751f7f23ee1d9697d44d2968df

vss.c: Don't try to mmap empty files

as this causes mmap() to return MAP_FAILED, i.e. para_mmap() calls
exit() so para_server dies, which clearly is inapproriate.  Instead,
skip the audio file and try the next one if size == 0.
