# _writegsbase_u32(), _writegsbase_u64()

Write the value to the GS base register. Both intrinsics are mapped to `WRGSBASE` instruction.

## Syntax

_writegsbase_u32(int 32 val)

extern void _writegsbase_u64(unsigned __int64 val);

## Arguments

val

  the value to be written to the GS base register

## Description

These intrinsics write the given value to the GS segment base register.
