Function Documentation

◆ gate_coroutine_supported()

GATE_CORE_API gate_bool_t gate_coroutine_supported ( )

Returns TRUE if coroutines are supported on this platform.

Returns
TRUE/FALSE indicating support for coroutines on this platform

◆ gate_coroutine_run()

GATE_CORE_API gate_result_t gate_coroutine_run ( gate_coroutine_function_t func,
void * param )

Starts a coroutine session and executes the first given coroutine.

Parameters
[in]funcfunction to be executed as first coroutine in a session
[in]paramparameter to be used in first coroutine entry point
Returns
GATE_RESULT_* result code

◆ gate_coroutine_enabled()

GATE_CORE_API gate_bool_t gate_coroutine_enabled ( )

Returns if a coroutine session is already running.

Returns
TRUE/FALSE indicating a running coroutine

◆ gate_coroutine_get_current()

GATE_CORE_API gate_result_t gate_coroutine_get_current ( gate_coroutine_id_t * ptr_id)

Returns the ID of the currently running coroutine.

Parameters
[in]ptr_idPointer to ID to be overwritten with the current coroutine ID
