How to Truncate a file opened by fopen()



Hi All,
 
    How can I truncate  a file opened by fopen() ?
 
    If I want to extend my file or truncate my file I have to use ftruncate, but ftruncate takes int (file descriptor) is there any function which takes FILE * ?
 
 
Thanks in advance
 
Best Regards,
