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.
