ZIP_SOURCE_ZIP(3)					     Library Functions Manual						 ZIP_SOURCE_ZIP(3)

NAME

       zip_source_zip - create data source from zip file

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       struct  zip_source  *  zip_source_zip(struct  zip *archive, struct zip *srcarchive); "zip_uint64_t srcidx" "int 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  contain-
       ing  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  com-
				     pressed 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.

NAME

       zip_fdopen - open zip archive using open file descriptor

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       struct zip * zip_fdopen(int fd, int flags, int *errorp);

DESCRIPTION

       The zip archive specified by the open file descriptor fd is opened and a pointer to a

       struct  zip,  used  to  manipulate the archive, is returned.  In contrast to zip_open(3), using the archive can only be opened in read-only
       mode.  The fd argument may not be used any longer after calling The are specified by or'ing the following values, or 0 for none of them.

	      ZIP_CHECKCONS  Perform additional consistency checks on the archive, and error if they fail.

       If an error occurs and errorp is it will be set to the corresponding error code.

RETURN VALUES

       Upon successful completion zip_fdopen returns a

       struct zip pointer, and fd should not be used any longer, nor passed to close(2).  Otherwise, NULL is returned and *errorp is set to  indi-
       cate the error.	In the error case, fd remains unchanged.

ERRORS

       The file specified by fd is prepared for use by libzip(3) unless:

	      [ZIP_ER_INCONS]
		  Inconsistencies were found in the file specified by path and ZIP_CHECKCONS was specified.

	      [ZIP_ER_INVAL]
		  The flags argument is invalid.  Not all zip_open(3) flags are allowed for see DESCRIPTION.

	      [ZIP_ER_MEMORY]
		  Required memory could not be allocated.

	      [ZIP_ER_NOZIP]
		  The file specified by fd is not a zip archive.

	      [ZIP_ER_OPEN]
		  The file specified by fd could not be prepared for use by libzip(3).

	      [ZIP_ER_READ]
		  A read error occurred; see for details.

	      [ZIP_ER_SEEK]
		  The file specified by fd does not allow seeks.
