#include <IO.h> int io_read_annotation( GapIO *io, int N, int *anno); int io_write_annotation( GapIO *io, int N, int *anno);
These functions read and write the first annotation number in the linked lists referenced by the reading and contig structures. For both functions, N is a reading number if it is above zero or a contig number when below zero (in which case it is negated).
io_read_annotation reads the annotations field of reading N
or contig -N and stores this in anno. It sets anno to 0
returns 1 for failure. Otherwise it returns 0.
io_write_annotation sets the annotations field of reading N
or contig -N to be *anno. Despite the fact that it is a pointer,
the contents of anno is not modified. It returns 1 for failure and 0 for
success (but currently always returns 0).
