Most C functions accepting a Nim string converted to a `cstring` will likely not need to keep this string around and by the time -they return the string won't be needed anymore. However, for the rare cases -where a Nim string has to be preserved and made available to the C backend -as a `cstring`, you will need to manually prevent the string data -from being freed with [GC_ref](system.html#GC_ref,string) and [GC_unref]( -system.html#GC_unref,string). +they return the string won't be needed anymore. A similar thing happens with C code invoking Nim code which returns a `cstring`. Consider the following proc: |
