Struct Context 

#[repr(C)]
pub struct Context {
    context_id: Id,
    log_level_pos: i32,
    log_level_ptr: *mut i8,
    trace_status_ptr: *mut i8,
    mcnt: u8,
}

This structure is used for every context used in an application.

Fields

context_id: Id

context id

log_level_pos: i32

offset in user-application context field

log_level_ptr: *mut i8

pointer to the log level

trace_status_ptr: *mut i8

pointer to the trace status

mcnt: u8

message counter

Implementations

impl Context

pub const fn empty() -> Self

pub const fn context_id(&self) -> &Id

pub fn log_level(&self) -> LogLevel

pub fn is_log_level_enabled(&self, level: LogLevel) -> bool

Checks the log level passed by the log function if enabled for that context or not.

This function can be called by applications before generating their logs. Also called before writing new log messages.

pub unsafe fn log( &self, level: LogLevel, buffer: *mut c_char, size: usize, args_num: i32, ) -> ReturnValue

Writes a log message to the DLT daemon.

Safety

This function is unsafe because it dereferences the buffer pointer. buffer must be a valid pointer to a buffer of size bytes.
