<nowiki>*</nowiki> Since 1.76, Sony has removed key information from sys_dynlib_get_info() (syscall 593), eg. it does not return the module's code base address, data base address, code size, or the data size.

<b>Note:</b> All system calls actually have the thread pointer as the first argument (struct thread *td), however since it's common among all system calls it's been omitted for readability.
