If .Ar freep is non-zero, the data will be freed when it is no longer needed. .Bd -literal struct zip_stat { zip_uint8_t *data; /* pointer to the actual data */ zip_uint64_t length; /* length of this fragment */ }; .Ed .Pp The data .Ar fragments point to must remain valid for the lifetime of the created source. .Ar fragments itself can be discarded once the source is created. .Pp The source can be used to open a zip archive from. .Sh RETURN VALUES Upon successful completion, the created source is returned. Otherwise, .Dv NULL is returned and the error code in .Ar archive or .Ar error is set to indicate the error. .Sh ERRORS .Fn zip_source_buffer and .Fn zip_source_buffer_create fail if: .Bl -tag -width Er .It Bq Er ZIP_ER_INVAL .Ar nfragments is greater than zero and .Ar fragments is .Dv NULL . .It Bq Er ZIP_ER_MEMORY Required memory could not be allocated. .El .Sh SEE ALSO .Xr libzip 3 , .Xr zip_file_add 3 , .Xr zip_file_replace 3 , .Xr zip_open_from_source 3 , .Xr zip_source 3 .Sh HISTORY .Fn zip_source_buffer_fragment and .Fn zip_source_buffer_fragment_create were added in libzip 1.4.0. .Sh AUTHORS .An -nosplit .An Dieter Baron Aq Mt dillo@nih.at and .An Thomas Klausner Aq Mt tk@giga.or.at
