ZIP_ADD(3)						     Library Functions Manual							ZIP_ADD(3)

NAME

       zip_add , - .Nm zip_replace add file to zip archive or replace file in zip archive

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       zip_int64_t zip_add(struct zip *archive, const char *name); "struct zip_source *source"

       int zip_replace(struct zip *archive, zip_uint64_t index); "struct zip_source *source"

DESCRIPTION

       The  function  zip_add  adds  a	file to a zip archive, while zip_replace replaces an existing file in a zip archive.  The argument archive
       specifies the zip archive to which the file should be added.  name is the file's name in the zip archive (for zip_add ), while index speci-
       fies  which  file  should  be  replaced (for zip_replace ).  The data is obtained from the source argument.  See the zip_source_* functions
       cited in SEE ALSO.

RETURN VALUES

       Upon successful completion, zip_add returns the index of the new file in the archive, and zip_replace returns 0.  Otherwise, -1 is returned
       and the error code in archive is set to indicate the error.

EXAMPLES

       struct zip_source *s;

       if ((s=zip_source_buffer(archive, buffer, len)) == NULL ||
	   zip_add(archive, name, s)  0) {
	   zip_source_free(s);
	   printf("error adding file: %s0, zip_strerror(archive)); }

ERRORS

       zip_add and zip_replace fail if:

	      [ZIP_ER_EXISTS]
		  There is already a file called name in the archive.  (Only applies to zip_add ).

	      [ZIP_ER_INVAL]
		  source or name are NULL, or index is invalid.

	      [ZIP_ER_MEMORY]
		  Required memory could not be allocated.

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.
