ZIP_FSEEK(3)               Library Functions Manual               ZIP_FSEEK(3)

NAME
     zip_fseek, zip_file_is_seekable - seek in file

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #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);

DESCRIPTION
     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.

RETURN VALUES
     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.

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