NAME

       zip_source_zip - create data source from zip file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       zip.h  zip_source_t  * zip_source_zip zip_t *archive zip_t *srcarchive zip_uint64_t srcidx
       zip_flags_t flags zip_uint64_t start zip_int64_t len

DESCRIPTION

       The function zip_source_zip creates a zip source from  a  file  in  a  zip  archive.   The
       srcarchive  argument  is  the  (open)  zip archive containing the source zip file at index
       srcidx.  len bytes from offset start will be used in the zip_source.  If len is 0  or  -1,
       the  rest  of the file, starting from start, is used.  If start is zero and len is -1, the
       whole file will be copied without decompressing it.

       Supported flags are:

       ZIP_FL_UNCHANGED
              Try to get the original data without  any  changes  that  may  have  been  made  to
              srcarchive after opening it.

       ZIP_FL_RECOMPRESS
              When  adding  the  data  from srcarchive, re-compress it using the current settings
              instead of copying the compressed data.

RETURN VALUES

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

ERRORS

       zip_source_zip fails if:

       [ZIP_ER_CHANGED] Unchanged data was requested, but it is not available.

       [ZIP_ER_INVAL]   srcarchive, srcidx, start, or len are invalid.

       [ZIP_ER_MEMORY]  Required  memory could not be allocated.  Additionally, it can return all
                        error codes from zip_stat_index and zip_fopen_index.
