Eclipse : GLib-ERROR

Eclipse : GLib-ERROR

I have an JAVA application for the fingerprint scanning and fingerprint
matching.For matching the finger prints I am using the libfprint library.I
have done all the settings related with the library.
The basic functions like initialization of library is work fine in the
application.Now am trying to allocate the memory for the image using the
function fpi_img_new() . Here is the syntax for that function
struct fp_img *fpi_img_new(size_t length);
but when I try to allocate some memory by passing the value to this
function it shows the following error
GLib-ERROR **: /build/buildd/glib2.0-2.30.0/./glib/gmem.c:170: failed to
allocate 3078340616 bytes
/usr/lib/jvm/java-7-openjdk/bin/java: line 31: 3078 Trace/breakpoint trap
$jre $args
I am passing the value manually to just check the functionality of this
function.But it gets fail. Could any one please help me in solving the
above problem? Thank you in advance.
