Takes a type-0x15 input buffer containing a [[#SystemDeliveryInfo]], no output.


This validates the [[#SystemDeliveryInfo]] HMAC and the protocol-version fields. Then the meta version is compared with a state field, an error is returned on match otherwise 0 is returned.
This validates the [[#SystemDeliveryInfo]] HMAC and the protocol-version fields. Then an error is returned when SystemUpdateMetaVersion is less than a state field, otherwise 0 is returned (state field originates from [[System_Settings|system-setting]] <code>contents_delivery!required_system_version_to_deliver_application</code>).


==== GetApplicationDeliveryInfo ====
==== GetApplicationDeliveryInfo ====
Takes a type-0x6 output buffer containing an array of [[#ApplicationDeliveryInfo]], an input u32 bitmask <code>nn::ns::ApplicationDeliveryAttributeTag</code>, an [[NCM_services#ApplicationId|ApplicationId]], and returns an output s32 total_out.
Takes a type-0x6 output buffer containing an array of [[#ApplicationDeliveryInfo|ApplicationDeliveryInfo]], an input u32 bitmask <code>nn::ns::ApplicationDeliveryAttributeTag</code>, an [[NCM_services#ApplicationId|ApplicationId]], and returns an output s32 total_out.


An error is thrown if any bit is set in ApplicationDeliveryAttributeTag besides bit1. The output array-count must be at least 1: only 1 entry will be written to this array (hence on success total_out will also only be 1 on success).
[11.0.0+] An error is thrown if LocalContentShare is not [[#IsLocalContentShareEnabled|enabled]].
 
An error is thrown if any bit is set in ApplicationDeliveryAttributeTag besides bit1, this must also be <=0x3. The output array-count must be at least 1: only 1 entry will be written to this array (hence on success total_out will also only be 1 on success).
 
An error is thrown if a state ref-count is zero.
 
An error is thrown if [[NIM_services|nim]] ListApplicationApplyDeltaTask returns a task.
 
HasApplicationRecord is called with the input [[NCM_services#ApplicationId|ApplicationId]], an error is returned if the record isn't found.
 
[[#ApplicationDeliveryInfo|RequiredApplicationVersion]] is initially set to the output version from [[Shared_Database_services|avm]] GetLaunchRequiredVersion. Later when ContentMetaType == Application etc, it calls a func. This func uses [[NCM_services|ncm]] IContentMetaDatabase GetRequiredApplicationVersion. If the output version is higher than the [[#ApplicationDeliveryInfo|RequiredApplicationVersion]] field then the output version is written here. Immediately aferwards, it also checks whether the bit for Compacted is set from [[NCM_services|ncm]] IContentMetaDatabase GetAttributes, clearing [[#ApplicationDeliveryInfo|ApplicationVersion]] if the attribute is set.
 
[20.0.0+] [[#ApplicationDeliveryInfo|ApplicationDeliveryInfo]] ContentMetaPlatform and ProperProgramExists are now set using data from [[NCM_services|ncm]].
 
[20.0.0+] [[Shared_Database_services|pl:s]] GetFunctionBlackListSystemVersionToAuthorize with ApplicationFunctionAuthorizationId=0x5 is now used, the output version is written to [[#ApplicationDeliveryInfo|RequiredSystemVersion]] when it's higher than the value previously written here.
 
[20.0.0+] [[Shared_Database_services|pl:s]] GetRequiredApplicationVersion with ApplicationFunctionAuthorizationId=0x5 is now used, the output version is written to [[#ApplicationDeliveryInfo|RequiredApplicationVersion]] when it's higher than the value previously written here.

The array-count for the second buffer must be 1, otherwise an error is returned.
 
This uses the same LocalContentShare check as [[#GetApplicationDeliveryInfo|GetApplicationDeliveryInfo]].
 
The second [[#ApplicationDeliveryInfo]] buffer is validated. An error is thrown when u32 [[#ApplicationDeliveryInfo]] (second buffer) +0x1C & 0x3 != 0x2, likewise when bit28 is clear in this field (bitmask 0x10000000).
 
The array-count for the first buffer must be <=1, otherwise an error is returned. If the array-count for the first buffer is 0, this will return 0 with the output bool set to 0. The first [[#ApplicationDeliveryInfo]] buffer is validated. An error is thrown when u32 [[#ApplicationDeliveryInfo]] (first buffer) +0x1C bit1 is clear or bit0 set. An error is thrown when u32 [[#ApplicationDeliveryInfo]] (second buffer) +0x1C bit1 is clear.
 
When u32 [[#ApplicationDeliveryInfo]] (first or second buffer) +0x14 is higher than [[#ApplicationDeliveryInfo]] (second buffer) ApplicationVersion, this will return 0 with the output bool set to 0.
 
When u32 [[#ApplicationDeliveryInfo]] (first buffer) +0x1C bit28 is set (bitmask 0x10000000):

The array-count for ContentMetaKey must be at least 1, and for ApplicationDeliveryInfo it must match 1.
The array-count for ContentMetaKey must be at least 1, and for ApplicationDeliveryInfo it must match 1.


This will only return 1 ContentMetaKey entry. This will not output the entry when the input s32 is larger than 0. This also does other validation, etc.
The [[#ApplicationDeliveryInfo|ApplicationDeliveryInfo]] is validated (ApplicationDeliveryProtocolVersion/HMAC). An error is thrown when [[#ApplicationDeliveryInfo|ApplicationDeliveryAttributeTag]] bit0 is set.
 
This uses the same ref-count check as [[#GetApplicationDeliveryInfo|GetApplicationDeliveryInfo]].

==== Cmd2019 ====
Takes a type-0x15 input buffer containing a [[#SystemDeliveryInfo]], a type-0x5 input buffer containing an array of [[#ApplicationDeliveryInfo]], a type-0x5 input buffer containing an array of [[#ApplicationDeliveryInfo]], returns an output u8 bool.
 
This is essentially an extended version of [[#CanDeliverApplication|CanDeliverApplication]], with additional functionality for determining platform compatibility.
 
This calls a func for validating the [[#SystemDeliveryInfo]] from the type-0x15 buffer, returning the Result on failure.
 
Then [[#CanDeliverApplication|CanDeliverApplication]] is called with the output bool and the input arrays, returning the Result on failure.
 
If the output bool is set after calling the above, it then calls a func with the output bool, the second [[#ApplicationDeliveryInfo]] buffer, and the [[#SystemDeliveryInfo]] from the type-0x15 buffer. This func does the following:
* When the SystemDeliveryInfoPlatform from the input [[#SystemDeliveryInfo]] matches the [[System_Settings|sys-setting]], it does the following:

[[NIM_services|NIM]] will use the input addr/port with [[Sockets_services|bind()]]. During [[Sockets_services|accept()]] handling the addr from there must match the input addr.
