nsis Services Service::Create

Example

##=
# The variable $Bit will hold either 64 or 32 depending on system architecture 
# This is used with all the ${Service::} macros
# Use this in the beginning of your code.
# This snippet should only be used once.
#
Var Bit
System::Call "kernel32::GetCurrentProcess()i.s"
System::Call "kernel32::IsWow64Process(is,*i.r0)"
StrCmpS $0 0 +3
StrCpy $Bit 64
Goto +2
StrCpy $Bit 32

##= 
#= Service::Create
#
# USAGE:
# ${Service::Create} "NAME" "PATH" "TYPE" "START" "DEPEND" /DISABLEFSR $0 $1
#
#    ::Create    = Creates a service entry in the registry and Service Database
#    NAME        = The Service name

#    TYPE        = own|share|interact|kernel|filesys|rec
#    START       = boot|system|auto|demand|disabled|delayed-auto
#    DEPEND      = Dependencies(separated by / (forward slash))
#    /DISABLEFSR = Disables redirection if x64. Use "" to skip.
#    $0          = Return after call
#    $1          =   ''    ''    ''

The /DISABLEFSR parameter should only be used on x64 machines. However, if you mess up there's a failsafe in the macros that will dodge this bullet for you. This applies to al the service macros listed here.
