fseek

Purpose

Set file position indicator.

Synopsis

status = fseek(fid, offset, 'origin')

Description

status = fseek(fid, offset, 'origin') repositions the file position indicator in the specified file to the specified byte offset for the specified origin. fid is a integer file identifier obtained from fopen.

offset values are interpreted as follows:

-------------------------------------------------------------------
offset > 0  Move position indicator offset bytes toward the end   
               of the file.                                          
offset = 0     Do not change position.                               
offset < 0  Move position indicator offset bytes toward the be    
               ginning of the file.                                  
-------------------------------------------------------------------
origin can be

-------------------------------------
'bof'  -1  Beginning of file.         
'cof'   0   Current position in file.  
'eof'   1   End of file.               
-------------------------------------
A status value for the operation is returned with value 0 on success and -1 on failure. If an error occurs, use the function ferror to get more information about the nature of the error.
