Manually sets the timeout for LJM's stream data collection. Writing to this configuration sets LJM_STREAM_RECEIVE_TIMEOUT_MODE to LJM_STREAM_RECEIVE_TIMEOUT_MODE_MANUAL.

Writing a non-zero value to LJM_STREAM_RECEIVE_TIMEOUT_MS will manually set the timeout for LJM's stream data collection. Note that using LJM_STREAM_RECEIVE_TIMEOUT_MODE of LJM_STREAM_RECEIVE_TIMEOUT_MODE_CALCULATED is almost always better than using manual non-zero LJM_STREAM_RECEIVE_TIMEOUT_MS value.

A value of 0 should not be written to LJM_STREAM_RECEIVE_TIMEOUT_MS. This corresponds to an infinite timeout period and it could lead to a deadlock condition in LJM. Instead, write a large non-zero value. This should only be necessary for externally clocked or triggered stream modes where the necessary clock/trigger may not occur within a normal milliseconds long timeout period.

The constant LJM_STREAM_RECEIVE_TIMEOUT_MS can be used interchangeably with the string "LJM_STREAM_RECEIVE_TIMEOUT_MS".


LJM_STREAM_RECEIVE_TIMEOUT_MS does not affect currently running or already initialized streams.

To read LJM_STREAM_RECEIVE_TIMEOUT_MS, use LJM_ReadLibraryConfigS.

To write LJM_STREAM_RECEIVE_TIMEOUT_MS, use LJM_WriteLibraryConfigS orLJM_LoadConfigurationFile.

LJM_STREAM_RECEIVE_TIMEOUT_MS affects the behavior of LJM_eStreamRead.


Set the LJM_STREAM_RECEIVE_TIMEOUT_MS mode to 5 seconds.

char ErrorString[LJM_MAX_NAME_SIZE];
int LJMError = 0;
LJMError = LJM_WriteLibraryConfigS(

    LJM_ErrorToString(LJMError, ErrorString);
    printf("LJM_WriteLibraryConfigS error: %s\n", ErrorString);
