Whether there is an upper limit on the parameters of the DAQmxReadAnalogF64 function

[astffsfffff]

float64 data[200000]={0};

DAQmxReadAnalogF64(taskHandle,-1,-1,DAQmx_Val_GroupByChannel,data,200000,&read,NULL);

The function will crash if it has more than 20k parameters or an array of more than 20k, is there an upper limit to this parameter, or is there a better way to receive a signal and extract 80k data
Thanks for the reply

Use dynamically allocated buffers (malloc) instead of stack allocated ones!
