[SAC-HELP] Not able to get complete header information by using C code

Sun Dec 25 05:12:55 PST 2011

I am writing C code to read sac file.
But what I have found that my out put sac file
does not contain all the header information as to my input sac file. 

I am using 
wsac1 (kname, yarray, &amp; npts, &amp;beg, &amp;del, &amp;nerr, strlen( out ));
to write it to the sac header.

Did i am doing some wrong or probably my code is not complete.
how to write the complete header information.

my read (in) header info
