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 argu‐
ment 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.

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));
}
