+WinFsp Launch API.
+
+In order to use the WinFsp Launch API a program must include <winfsp/launch.h>
+and link with the winfsp$$_$$x64.dll (or winfsp$$_$$x86.dll) library.
+
+== Launch Control
+
+=== Functions
+
+*FspLaunchCallLauncherPipe* - Call launcher pipe.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchCallLauncherPipe( 
+    WCHAR Command,
+    ULONG Argc,
+    PWSTR *Argv,
+    ULONG *Argl, 
+    PWSTR Buffer,
+    PULONG PSize,
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _Command_ - Launcher command to send. For example, the 'L' launcher command instructs
+the launcher to list all running service instances.
+- _Argc_ - Command argument count. May be 0.
+- _Argv_ - Command argument array. May be NULL.
+- _Argl_ - Command argument length array. May be NULL. If this is NULL all command arguments
+are assumed to be NULL-terminated strings. It is also possible for specific arguments
+to be NULL-terminated; in this case pass -1 in the corresponding Argl position.
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+This function is used to send a command to the launcher and receive a response.
+
+
+*FspLaunchGetInfo* - Get information about a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchGetInfo( 
+    PWSTR ClassName,
+    PWSTR InstanceName, 
+    PWSTR Buffer,
+    PULONG PSize, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to stop.
+- _InstanceName_ - Instance name of the service instance to stop.
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+The information is a list of NULL-terminated strings: the class name of the service instance,
+the instance name of the service instance and the full command line used to start the service
+instance.
+
+
+*FspLaunchGetNameList* - List service instances.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchGetNameList( 
+    PWSTR Buffer,
+    PULONG PSize, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+The information is a list of pairs of NULL-terminated strings. Each pair contains the class
+name and instance name of a service instance. All currently running service instances are
+listed.
+
+
+*FspLaunchStart* - Start a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchStart( 
+    PWSTR ClassName,
+    PWSTR InstanceName,
+    ULONG Argc,
+    PWSTR *Argv, 
+    BOOLEAN HasSecret, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to start.
+- _InstanceName_ - Instance name of the service instance to start.
+- _Argc_ - Service instance argument count. May be 0.
+- _Argv_ - Service instance argument array. May be NULL.
+- _HasSecret_ - Whether the last argument in Argv is assumed to be a secret (e.g. password) or not.
+Secrets are passed to service instances through standard input rather than the command
+line.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+
+*FspLaunchStop* - Stop a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchStop( 
+    PWSTR ClassName,
+    PWSTR InstanceName, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to stop.
+- _InstanceName_ - Instance name of the service instance to stop.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+
+== Service Registry
+
+=== Functions
+
+*FspLaunchRegFreeRecord* - Free a service registry record.
+
+[source,c]
+----
+FSP_API VOID FspLaunchRegFreeRecord( 
+    FSP_LAUNCH_REG_RECORD *Record);  
+----

+----
+FSP_API NTSTATUS FspLaunchRegGetRecord(

+    PWSTR Agent, 
+    FSP_LAUNCH_REG_RECORD **PRecord);  
+----
+
+*Parameters*
+
+- _ClassName_ - The service class name.
+- _Agent_ - The name of the agent that is retrieving the service record. This API matches
+the supplied Agent against the Agent in the service record and it only returns
+the record if they match. Pass NULL to match any Agent.
+- _PRecord_ - Pointer to a record pointer. Memory for the service record will be allocated
+and a pointer to it will be stored at this address. This memory must be later
+freed using FspLaunchRegFreeRecord.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS or error code.
+
+*See Also*
+
+- FspLaunchRegFreeRecord
+
+
+*FspLaunchRegSetRecord* - Add/change/delete a service registry record.
+
+[source,c]
+----

+    const FSP_LAUNCH_REG_RECORD *Record);  
+----
+
+*Parameters*
+
+- _ClassName_ - The service class name.
+- _Record_ - The record to set in the registry. If NULL, the registry record is deleted.
+
+*Return Value*
