SYNOPSIS
#include <zip.h>

zip_int64_t zip_file_add(struct zip *archive, const char *name); "struct zip_source *source" "zip_flags_t flags"

int zip_file_replace(struct zip *archive, zip_uint64_t index); "struct zip_source *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 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 the zip_source_* functions cited in SEE ALSO.

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
struct zip_source *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_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).
