Subject: Adding pointer dereferencing after calling dlsym()
X-Git-Tag: fuse-3.2.1~6
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d92bf83;p=qemu-gpiodev%2Flibfuse.git

Adding pointer dereferencing after calling dlsym()
dlsym() resolves the location of the loaded symbol,
therefore dlsym() returns the type (fuse_module_factory_t *), not (fuse_module_factory_t).
Added pinter dereferencing to correctly refer the factory function.
