LIBRARY

libzip (-lzip)

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: %sn", zip_strerror(archive)); 
}

ERRORS

zip_add() and zip_replace() fail if:
[ZIP_ER_EXISTS]
There is already a file called name in the archive. (Only applies to zip_add()).
[ZIP_ER_INVAL]
source or name are NULL, or index is invalid.
[ZIP_ER_MEMORY]
