plucky (3) zip_fseek.3.gz

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.
