| | | | | | | | | | | | | | | | | | | | | the supplied option. This allows the following templates to be supplied to set multiple members of a struct at the same time. e.g. #define FUSE_LIB_OPT(t, p, v) { t, offsetof(struct fuse_config, p), v } static const struct fuse_opt fuse_lib_opts[] = { FUSE_LIB_OPT("gid=", set_gid, 1), FUSE_LIB_OPT("gid=%u", gid, 0), FUSE_OPT_END }; If "-ogid=1000" is passed to fuse_opt_parse(3) it will set both: fuse_config.set_gid=1 fuse_config.gid=1000 ok mpi@
* The fuse_opt_match(3) library function does not match options correctly.helg2017-12-111-57/+19
| | | | | | | | | | | | | | | | | | libfuse supports option templates of the following form that can be used to automatically parse arguments supplied on the command line. "-p " argument that takes an option e.g -p 22 or -p22 "-p %x" argument that takes an option parsed like sscanf(3) "cache=yes" matches -ocache=yes or -o cache=yes "cache=%s" matches -ocache=<string> or -o cache=<string> "cache=" matches same as above but value is passed to option proc "noatime" matches -onoatime or -o atime For example, it does not match options of the form "-p 22" or "cache=yes" to the corresponding templates "-p " and "cache=yes". This patch fixes that and updates the regression tests accordingly. ok mpi@
