| .Sh NAME |
| .Nm zip_source_buffer_fragment , |
| .Nm zip_source_buffer_fragment_create |
| .Nd create zip data source from multiple buffer |
| .Sh LIBRARY |
| libzip (-lzip) |
| .Sh SYNOPSIS |
| .In zip.h |
| .Ft zip_source_t * |
| .Fn zip_source_buffer_fragment "zip_t *archive" "zip_buffer_fragment_t *fragments" "zip_uint64_t nfragments" "int freep" |
| .Ft zip_source_t * |
| .Fn zip_source_buffer_fragment_create "zip_buffer_fragment_t *fragments" "zip_uint64_t nfragments" "int freep" "zip_error_t *error" |
| .Sh DESCRIPTION |
| The functions |
| .Fn zip_source_buffer_fragment |
| and |
| .Fn zip_source_buffer_fragment_create |
| create a zip source from the data in |
| .Ar fragments . |
| .Ar nfragments |
| specifies the number of fragments. |
| 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. |
