@param [in] stream - Stream identifier @param [in] ptr - Pointer to memory object allocated using ‘hipMallocSignalMemory’ flag @param [in] value - Value to be used in compare operation @param [in] flags - Defines the compare operation, supported values are hipStreamWaitValueGte hipStreamWaitValueEq, hipStreamWaitValueAnd and hipStreamWaitValueNor @param [in] mask - Mask to be applied on value at memory before it is compared with value, default value is set to enable every bit

@returns #hipSuccess, #hipErrorInvalidValue

Enqueues a wait command to the stream, all operations enqueued on this stream after this, will not execute until the defined wait condition is true.

hipStreamWaitValueGte: waits until *ptr&mask >= value hipStreamWaitValueEq : waits until *ptr&mask == value hipStreamWaitValueAnd: waits until ((*ptr&mask) & value) != 0 hipStreamWaitValueNor: waits until ~((*ptr&mask) | (value&mask)) != 0

@note when using ‘hipStreamWaitValueNor’, mask is applied on both ‘value’ and ‘*ptr’.

@note Support for hipStreamWaitValue32 can be queried using ‘hipDeviceGetAttribute()’ and ‘hipDeviceAttributeCanUseStreamWaitValue’ flag.

@warning This API is marked as beta, meaning, while this is feature complete, it is still open to changes and may have outstanding issues.
