NAME

SYNOPSIS
#include <zip.h>
zip_int64_t
zip_add(struct zip *archive, const char *name, struct zip_source *source);
int
zip_replace(struct zip *archive, zip_uint64_t index, struct zip_source *source);

DESCRIPTION
The function zip_add() adds a file to a zip archive, while zip_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_add()), while index specifies which file should be replaced (for zip_replace()). The data is obtained from the source argument. See the zip_source_*() functions cited in SEE ALSO.

RETURN VALUES
Upon successful completion, zip_add() returns the index of the new file in the archive, and zip_replace() returns 0. Otherwise, -1 is returned and the error code in archive is set to indicate the error.

EXAMPLES

    struct zip_source *s;
    if ((s=zip_source_buffer(archive, buffer, len)) == NULL ||
        zip_add(archive, name, s)  0) {
        zip_source_free(s);
        printf("error adding file: %s, zip_strerror(archive));
    }
