[igraph] igraph_i_decompose_free

[John Lapeyre]

Hi,

There is a function in components.c called 
igraph_i_decompose_free. But its protoypte does
not appear in any header and it is not documented.
It would be nice to include it, because, if not, users
will have to write it to use igraph_decompose.


The documentation for igraph_decompose suggests freeing the
memory by hand. You can read...

  Don't forget to call igraph_destroy() and igraph_free() on
  the elements of this pointer vector to free unneeded
  memory.

However, the string igraph_free does not appear elsewhere in
the documentation. Its prototype is in memory.h, but this
header file is apparantly not installed for the users of the
library.

Thanks,
John
