Data Structure Documentation

struct cy_stc_ipc_sema_t

Data Fields
uint32_t	maxSema	Maximum semaphores in system. Must be a multiple of 32. This count applies to both secure and non-secure semaphores
uint32_t *	arrayPtr	Pointer to semaphores array. Must have length maxSema / 32. This must be located in memory which is accessible to all processing environments which will interact with semaphores.

Return constants for IPC semaphores functions.

Enumerator
CY_IPC_SEMA_SUCCESS	No error has occurred.
CY_IPC_SEMA_ERROR_LOCKED	Semaphores IPC channel has already been locked.
CY_IPC_SEMA_ERROR_UNLOCKED	Semaphores IPC channel is unlocked.
CY_IPC_SEMA_BAD_PARAM	Semaphore API bad parameter.
CY_IPC_SEMA_OUT_OF_RANGE	Semaphore API return when semaphore number is out of the range.
CY_IPC_SEMA_NOT_ACQUIRED	Semaphore API return when IPC channel was not acquired.
CY_IPC_SEMA_LOCKED	Semaphore API return status when semaphore channel is busy or locked by another process.
CY_IPC_SEMA_STATUS_LOCKED	Semaphore status return that the semaphore is set.
CY_IPC_SEMA_STATUS_UNLOCKED	Semaphore status return that the semaphore is cleared.
