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).


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.


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)); }


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.
