it probably means i didn't consider closely enough when to free
the string passed to plinitlabel etc, and never noticed the program
growing.  i think most of the other strdup'd values are freed correctly.

as several people have said, the result of strdup must
be freed explicitly somewhere.

greetings,

is tcs, the unix version, considered "free"? may i use it if i remember to keep
copyright notices and such?

No!
It's mainly my part in making tcs(1) to library.  It's expensive to
convert ISO-2022-JP to utf or vise versa.  I'm now in the process of updating
this, however, it's hard enough to me. :-)  Many strange behaviour have I.

You'll need to free each string when you know
it is no longer in use.

Anyone ported Bohem's garbage collector to Plan 9?

Alternatively, anyone ported Limbo to Plan 9? :-)

I'm facing memory problem in news reader having
more than 2000 unread articles which
uses the strdup() more than 2000 times, and 
then  fails in malloc. 

Is this mean not to use strdup() in that situation?
