[Mspgcc-users] Sprintf warning/error

[Stokes, Mark]

When using sprintf with float variables, I get the following warning (and the 
output
string gives a "(NULL)" in the place of the variable).

warning: passing arg 1 of `sprintf' from incompatible pointer type
warning: double format, float arg (arg 3)
warning: double format, float arg (arg 3)

Example code:
void showfloat( )
{
float tempfloat;
char *buf[20];

    tempfloat = 9.40;
    sprintf( buf, "%.0f", tempfloat );
    usart1Puts( buf );
}

Is there a workaround for this?
Thanks
