ZIP_SOURCE_WINDOW_CREATE(3)                           Library Functions Manual

NAME
     zip_source_window_create - create zip data source overlay

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #include <zip.h>

     zip_source_t *
     zip_source_window_create(zip_source_t *source, zip_uint64_t start,
         zip_int64_t len, zip_error_t *error);

DESCRIPTION
     The zip_source_window_create() function create a zip source from an
     underlying zip source, restricting access to a particular window starting
     at byte start and having size len.  If len is -1, the window spans to the
     end of the underlying source.

     zip_source_window() and zip_source_window_create() don't take ownership
     of source.  The caller is responsible for freeing it.  (This is different
     to other layered sources.)

RETURN VALUES
     Upon successful completion, the created source is returned.  Otherwise,
     NULL is returned and the error code in error is set to indicate the
     error.

ERRORS
     zip_source_window_create() fails if:

     [ZIP_ER_INVAL]     src is NULL; there is an integer overflow adding start
                        and len; or len is less than -1.

     [ZIP_ER_MEMORY]    Required memory could not be allocated.
