IsIsrTid()

bool stk::IsIsrTid ( TId tid )

inlinestatic

Test whether a task identifier represents an ISR context.

Returns true if tid was produced by GetTid() called from an interrupt service routine, i.e. its upper 20 bits match TID_ISR_N. Use this predicate instead of comparing against TID_ISR_N directly.

Parameters

[in]

tid

Task identifier to test.

Returns

true if tid encodes an ISR context, false otherwise.

Note

ISR-safe (bitmask arithmetic only, no kernel calls).

SleepMs()

Put calling process into a sleep state.

Note

ms

Sleep time (milliseconds). 0 does not cause yield, use Yield instead. Negative will cause an assertion.

Warning

TID_ISR_N

TId stk::TID_ISR_N = static_cast<TId>(0xFFFFF000U)

staticconstexpr

Bitmask sentinel for ISR-context task identifiers.

The upper 20 bits of the TId space are reserved for ISR contexts. When GetTid() is called from an interrupt service routine, it returns TID_ISR_N | exception_number, where exception_number is the raw value:

//  bits[31:12] = 0xFFFFF (this sentinel mask)
//  bits[11:0]  = exception number

This encoding guarantees uniqueness per exception, so two ISRs at different priority levels or with different exception numbers are never treated as the same owner by synchronization primitives.

Task TIds are word-aligned pointers. On all supported Cortex-M and RISC-V targets they fall in the range 0x00000000..0xEFFFFFFF, so no overlap with the 0xFFFFF000..0xFFFFFFFF sentinel range is possible.

Note

Use IsIsrTid() to test for this sentinel rather than comparing against this constant directly.
