Change thread entry function and timer expiration function prototypes…

[phuerta79]

These functions have an ULONG type param, so if you want to pass a pointer to something you can cast it and it will fit in the ULONG param in 32 bit machines. But in 64 bit machines the pointer will not fit, so I propose to change this param to ALIGN_TYPE type.

For example, the following code will work in 32 bit machines, but it will not work on 64 bit machines:

struct my_object_type;

void my_thread_example_entry(ULONG param)
{
struct my_object_type *obj = (struct my_object_type *)param;
. . . 
}

void    tx_application_define(void *first_unused_memory)
{
 . . . 
tx_thread_create(&thread_1, "thread 1", my_thread_example_entry, (ULONG)&my_object,  
            stack_start, STACK_SIZE, 16, 16, 4, TX_AUTO_START);

. . . 
}

With the changes proposed, the code will turn into:

struct my_object_type;

void my_thread_example_entry(ALIGN_TYPE param)
{
struct my_object_type *obj = (struct my_object_type *)param;
. . . 
}

void    tx_application_define(void *first_unused_memory)
{
 . . . 
tx_thread_create(&thread_1, "thread 1", my_thread_example_entry, (ALIGN_TYPE )&my_object,  
            stack_start, STACK_SIZE, 16, 16, 4, TX_AUTO_START);

. . . 
}

And it will work ok both in 32 and 64 bit systems.

This Contribution License Agreement (“Agreement”) is agreed to by the party signing below (“You”),
and conveys certain license rights to Microsoft Corporation and its affiliates (“Microsoft”) for Your
contributions to Microsoft open source projects. This Agreement is effective as of the latest signature

1. Definitions.
   “Code” means the computer software code, whether in human-readable or machine-executable form,
   that is delivered by You to Microsoft under this Agreement.
   “Project” means any of the projects owned or managed by Microsoft and offered under a license
   approved by the Open Source Initiative (www.opensource.org).
   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
   associated comments and documentation.
2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any
   Project. This Agreement covers any and all Submissions that You, now or in the future (except as
   described in Section 4 below), Submit to any Project.
3. Originality of Work. You represent that each of Your Submissions is entirely Your original work.
   Should You wish to Submit materials that are not Your original work, You may Submit them separately
   to the Project if You (a) retain all copyright and license information that was in the materials as You
   received them, (b) in the description accompanying Your Submission, include the phrase “Submission
   containing materials of a third party:” followed by the names of the third party and any licenses or other

   guidelines concerning Submissions.
4. Your Employer. References to “employer” in this Agreement include Your employer or anyone else
   for whom You are acting in making Your Submission, e.g. as a contractor, vendor, or agent. If Your
   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
   desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
   and secure permission from the new employer before Submitting those Submissions.
5. Licenses.

• Copyright License. You grant Microsoft, and those who receive the Submission directly or
  indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license in the
  Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute
  the Submission and such derivative works, and to sublicense any or all of the foregoing rights to third

Hi @phuerta79 - I would like to make this change, but we are discussing this internally. In the meantime, you can use these extensions to pass 64-bit values to threads: https://github.com/azure-rtos/threadx/blob/master/common/inc/tx_api.h#L234-L259
You may need to modify your tx_port.h file, as done here: https://github.com/azure-rtos/threadx/blob/master/ports_smp/cortex_a5x_smp/gnu/inc/tx_port.h#L281

[phuerta79]

Hi @goldscott ,
Thanks for your feedback. I will take a look at what yo propose.

[fdesbiens]

Hi @phuerta79.

I am closing older PRs submitted before Microsoft contributed Azure RTOS to the Eclipse Foundation. The codebase has changed since 2023, and our opinion on specific matters could differ from Microsoft's.

If you still want this change to be merged into Eclipse ThreadX, please create a new pull request against the dev branch of this repository.

Before doing so, you must sign the Eclipse Contributor Agreement (ECA). The purpose of the ECA is to provide a written record that you have agreed to provide your code and documentation contributions under the licenses used by the Eclipse ThreadX project. It also makes it clear that you are promising that what you are contributing to Eclipse is code you wrote, and you have the necessary rights to contribute it to our projects. And finally, it documents a commitment from you that your open source contributions will be permanently on the public record.

Signing the ECA requires an Eclipse Foundation account if you do not already have one. You can create one for free at https://accounts.eclipse.org.

Be sure to use the same email address when you register for the account that you intend to use on Git commit records. Also, please add your GitHub ID to your Eclipse account. This enables synchronisation between Eclipse-owned infrastructure and GitHub.

Here is the link to sign the ECA:
