zip_source_buffer_fragment, zip_source_buffer_fragment_create
create zip data source from multiple buffer

libzip (-lzip)

#include <zip.h>

zip_source_t *
zip_source_buffer_fragment(zip_t *archive, zip_buffer_fragment_t *fragments, zip_uint64_t nfragments, int freep);

zip_source_t *
zip_source_buffer_fragment_create(zip_buffer_fragment_t *fragments, zip_uint64_t nfragments, int freep, zip_error_t *error);

The functions zip_source_buffer_fragment() and zip_source_buffer_fragment_create() create a zip source from the data in fragments. nfragments specifies the number of fragments. If freep is non-zero, the data will be freed when it is no longer needed.
struct zip_stat {
    zip_uint8_t *data;    /* pointer to the actual data */
    zip_uint64_t length;  /* length of this fragment */

The data fragments point to must remain valid for the lifetime of the created source. fragments itself can be discarded once the source is created.

The source can be used to open a zip archive from.

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

zip_source_buffer() and zip_source_buffer_create() fail if:
nfragments is greater than zero and fragments is NULL.
Required memory could not be allocated.

zip_source_buffer_fragment() and zip_source_buffer_fragment_create() were added in libzip 1.4.0.
