I would say your best bet is to use fread(3) and fwrite(3) to make
an non-ascii file of data structures.  This will help you save the
data part (i.e. the non-pointer data) somewhere neatly.  However,
you have to remember that if you stow some data in a file, and then
load it up again in another program, it may reside in a different
place in memory, and therefore your pointers will be different.  
Maybe a better idea is to put all of the data structures into an array,
replacing the pointers with integer array indices.  It is easy enough
then to rebuild your structures after reading the arrays out of a file
using fread.
