add directory to zip archive

libzip (-lzip)

#include <zip.h>

zip_dir_add(zip_t *archive, const char *name, zip_flags_t flags);

The function zip_dir_add() adds a directory to a zip archive. The argument archive specifies the zip archive to which the directory should be added. name is the directory's name in the zip archive.

This function adds an entry to the archive. It does not check whether a directory with that name exists in the file system, nor does it add its contents if it does. The flags argument can be any of:

Guess encoding of name (default). (Only CP-437 and UTF-8 are recognized.)
Interpret name as UTF-8.
Interpret name as code page 437 (CP-437).

Upon successful completion, the index of the new entry in the archive is returned. Otherwise, -1 is returned and the error code in archive is set to indicate the error.

zip_dir_add() fails if:
There is already an entry called name in the archive.
archive or name are NULL, or invalid UTF-8 encoded file names.
Required memory could not be allocated.
