You will want to check out the G_*_FORMAT macros here: http://developer.gnome.org/doc/API/2.0/glib/glib-Miscellaneous-Macros.html#G-GINT16-FORMAT:CAPS

but here no G_GINT_FORMAT

I haven't tested it, but you should be able to do:

Code: (Plaintext)
1 2 3 4	gint x; gint16 y; x = (gint) y;

The only problem with that is you have to make sure that your gint16 isn't out of bounds ...

actually wht i need is suppose i have gdkcolor *collor="#FFFFFF";
from iiam geting the values of red ,blue green by usiing color.red,color.green,color.blue,
all these r gint16 variables.
so i want to convert it into gint.
suppose from the above
red==255, like this

Well, you just have to look at the bounds as defined on: http://developer.gnome.org/doc/API/2.0/glib/glib-Basic-Types.html#gint

gint16 is defined as a short integer, which is 16 bits. gint is an integer, which is 32 bits.

Therefore, you should be able to cast in the same way as you would in C:

Code: (Plaintext)
1	gint red = (gint) color.red;

finally done this
by simply dividing the gint16 number with 256 to get the gint value
