NAME

zip_fseek, zip_file_is_seekable —

seek in file

LIBRARY

libzip (-lzip)

#include <zip.h>

zip_int8_t
zip_fseek(zip_file_t *file, zip_int64_t offset, int whence);

int
zip_file_is_seekable(zip_file_t *file);

The zip_fseek() function seeks to the specified offset relative to whence, just like fseek(3).

zip_fseek only works on uncompressed (stored), unencrypted data. When called on compressed or encrypted data it will return an error.

The zip_file_is_seekable() function returns 1 if a file is seekable.

If successful, zip_fseek() returns 0. Otherwise, -1 is returned.

zip_file_is_seekable() returns 1 if a file is seekable and 0 if not. On an invalid argument, it returns -1.

zip_fseek() was added in libzip 1.2.0. zip_file_is_seekable() was added in libzip 1.9.0.
