Struct HandleInfo 

#[repr(C)]
pub struct HandleInfo {
    pub resource_type: u32,
    pub permissions: u32,
    pub resource: u64,
}

Information about a capability handle (returned by SYS_HANDLE_INFO).

Fields

resource_type: u32

Resource type (file, memory, IPC, etc.).

permissions: u32

Permission bits (read, write, execute, grant, revoke).

resource: u64

Underlying resource identifier (fd, memory region ID, etc.).
