oracle pro*C problem:varchar variable is truncated after calling C function

[manoj339]

I have varchar variable declared .When I print this var it shows me correct value before a C function.
Inside a c function this variable value is getting truncated .
The c function does not pass this variable .It intializes structure memebers only.
I am using Pro*C/C++: Release 8.1.7.0.0 and OS details is :
Release: 5.8
Kernel architecture: sun4u
Application architecture: sparc
Hardware provider: Sun_Microsystems
Domain:
Kernel version: SunOS 5.8 Generic 117350-35 Mar 2006

Request your help in this matter.
