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 specifies 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.
