Error 903 -> malloc() failure

[Kay Kay]

Hey,

        I have problem with a program. While I was trying to run the program, its giving me an error 903 which mean malloc() failure. I couldn't understand what's really happening. I tried changing few parameters but it did not work. Any suggestions ?

PS: Please find the screen shot attached to this e-mail. If you wish to go through the VI once, I am also attaching the VI, instrument library. I appreciate your support.

Kay Kay,

Malloc stands for "memory allocation" and is a C command used to dynamically allocated your computer's memory. It sounds like there may be an error in the dll that your vis are calling into. Where did you get your instrument driver? Did you download it from the National Instruments website? What instrument was this set of vis intended to control?

Hey Chris,

                   We bought the instrument from NI website but it was developed by Z-Tec Instruments. Anyway, I resolved my problem. Thanks for your support.

Hey Chris,

                  I have'nt exactly discover something to solve my malloc() problem, but I would love to explain what I exactly did to resolve my issue. Intially, I configured the program such that there is no waveform information and I am asking a function to plot it. And then, I realised that I don't even have the data stored to plot. After that, I've used waveform preamble function which already exists in the instrument library to get the waveform details and then I passed that through auto config block and then passed the signal to the waveform read block and there I got the output waveform without any problem.

PS: It is confusing but this is what I did to resolve my issue.
