This is not regular C and won't compile as is.
You have to look elsewhere to find __user definition. It is very likely a macro that expands to something else, possibly nothing.

huge_val
INFINITY(3) Linux Programmer's Manual INFINITY(3)
NAME
INFINITY, NAN, HUGE_VAL, HUGE_VALF, HUGE_VALL - floating-point constants
SYNOPSIS
#define _ISOC99_SOURCE /* See feature_test_macros(7) */
#include <math.h>
INFINITY
NAN
HUGE_VAL
HUGE_VALF
HUGE_VALL
DESCRIPTION
The macro INFINITY expands to a float constant representing positive infinity.
The macro NAN expands to a float constant representing a quiet NaN (when supported). A quiet NaN is a NaN ("not-a-number") that does not
raise exceptions when it is used in arithmetic. The opposite is a signaling NaN. See IEC 60559:1989.
The macros HUGE_VAL, HUGE_VALF, HUGE_VALL expand to constants of types double, float and long double, respectively, that represent a large
positive value, possibly plus infinity.
CONFORMING TO
C99.
AVAILABILITY
On a glibc system, the macro HUGE_VAL is always available. Availability of the NAN macro can be tested using #ifdef NAN, and similarly for
INFINITY, HUGE_VALF, HUGE_VALL. They will be defined by <math.h> if _ISOC99_SOURCE or _GNU_SOURCE is defined, or __STDC_VERSION__ is
defined and has a value not less than 199901L.
