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_fopen , - .Nm zip_fopen_index open file in zip archive for reading

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       struct zip_file * zip_fopen(struct zip *archive, const char *fname, int flags);

       struct zip_file * zip_fopen_index(struct zip *archive, zip_uint64_t index, int flags);

DESCRIPTION

       The zip_fopen function opens the file name fname in archive.  The flags argument specifies how the name lookup should be done, according to
       the values are described in zip_name_locate(3).	Also, the following values may be or'ed to it.

	      ZIP_FL_COMPRESSED  Read the compressed data.  Otherwise the data is uncompressed by zip_fread.

	      ZIP_FL_UNCHANGED	 Read the original data from the zip archive, ignoring any changes made to the file.

       The zip_fopen_index function opens the file at position index.

       If encrypted data is encountered, the functions call zip_fopen_encrypted(3) or zip_fopen_index_encrypted(3) respectively, using the default
       password set with zip_set_default_password(3).

RETURN VALUES

       Upon successful completion, a

       struct zip_file pointer is returned.  Otherwise, NULL is returned and the error code in archive is set to indicate the error.

ERRORS

	      [ZIP_ER_CHANGED]
		  The file data has been changed.

	      [ZIP_ER_COMPNOTSUPP]
		  The compression method used is not supported.

	      [ZIP_ER_ENCRNOTSUPP]
		  The encryption method used is not supported.

	      [ZIP_ER_MEMORY]
		  Required memory could not be allocated.

	      [ZIP_ER_READ]
		  A file read error occurred.

	      [ZIP_ER_SEEK]
		  A file seek error occurred.

	      [ZIP_ER_ZLIB]
		  Initializing the zlib stream failed.

       The function zip_fopen may also fail and set for any of the errors specified for the routine zip_name_locate(3).

       The function zip_fopen_index may also fail with ZIP_ER_INVAL if index is invalid.
