| .SH "DESCRIPTION" |
| The |
| \fBzip_fseek\fR() |
| function seeks to the specified |
| \fIoffset\fR |
| relative to |
| \fIwhence\fR, |
| just like |
| fseek(3). |
| .PP |
| \fBzip_fseek\fR |
| only works on uncompressed (stored), unencrypted data. |
| When called on compressed or encrypted data it will return an error. |
| .PP |
| The |
| \fBzip_file_is_seekable\fR() |
| function returns 1 if a file is seekable. |
| .SH "RETURN VALUES" |
| If successful, |
| \fBzip_fseek\fR() |
| returns 0. |
| Otherwise, \-1 is returned. |
| .PP |
| \fBzip_file_is_seekable\fR() |
| returns 1 if a file is seekable and 0 if not. |
| On an invalid argument, it returns \-1. |
