More than three hours worked yours test.tcl - mistakes are not present.
Probably in my case there were problems with early versions of a kernel (2.6.8).
Probably it were hardware problems - now those two computers are not
accessible to me to check...
The message "invalid argument" could arise on fault owtcl but only when the
second argument at:: OW:: put is not specified (fixed).
One more mistake: check of returned value of function FS_write (error if
not zero). This function returns positive value in case of success, but in
swig/ow.i is written:
int put( const char * path, const char * value ) {
...
if ( FS_write(path,value,s,0) ) return 0 ;
return 1 ;
}
Fixed in owtcl only!
