NAME

       zip_file_add, zip_file_replace - add file to zip archive or replace file in zip archive

LIBRARY

       libzip (-lzip)

SYNOPSIS

       zip.h zip_int64_t zip_file_add zip_t *archive const char *name zip_source_t *source zip_flags_t flags int
       zip_file_replace zip_t *archive zip_uint64_t index zip_source_t *source zip_flags_t flags

DESCRIPTION

       The  function zip_file_add adds a file to a zip archive, while zip_file_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_file_add), while index specifies which file should be
       replaced  (for zip_file_replace).  The flags argument can be any combination of ZIP_FL_OVERWRITE with one
       of ZIP_FL_ENC_*:

       ZIP_FL_OVERWRITE
              Overwrite any existing file of the same name.  For zip_file_add only.

       ZIP_FL_ENC_GUESS
              Guess encoding of name (default).

       ZIP_FL_ENC_UTF_8
              Interpret name as UTF-8.

       ZIP_FL_ENC_CP437
              Interpret name as code page 437 (CP-437).  The data is obtained  from  the  source  argument,  see
              zip_source(3).

RETURN VALUES

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

EXAMPLES

       zip_source_t *s;
       const char buf="teststring";

       if ((s=zip_source_buffer(archive, buffer, sizeof(buf), 0)) == NULL ||
           zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) < 0) {
           zip_source_free(s);
           printf("error adding file: %s\n", zip_strerror(archive));
       }

ERRORS

       zip_file_add and zip_file_replace fail if:

       [ZIP_ER_EXISTS]  There  is already a file called name in the archive.  (Only applies to zip_file_add, and
                        only if ZIP_FL_OVERWRITE is not provided).

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

       [ZIP_ER_MEMORY]  Required memory could not be allocated.

       [ZIP_ER_RDONLY]  Archive was opened in read-only mode.
