Function dr_syscall_get_result_ex 

pub unsafe extern "C" fn dr_syscall_get_result_ex(
    drcontext: *mut c_void,
    info: *mut dr_syscall_result_info_t,
) -> bool_

Usable only from a post-syscall (dr_register_post_syscall_event()) event. Returns whether it successfully retrieved the results of the system call into \p info.

The caller should set the \p size, \p use_high, and \p use_errno fields of \p info prior to calling this routine. See the fields of #dr_syscall_result_info_t for details.
