semaphore+global+reentrant and functional global

[Brian001]

i implement a VI which uses global variable to store data, semaphore to make sure synchronization and makes the VI reentrant. the vi include initialization, read, write functions

the VI seems to implement all function provided by functional global.

can anyone tell me what is the difference between them about memory usage, performance? or they are exactly same?

thanks

Hello Brain,

I think you can take this thread as a good reference about globals.

Hope this link helps 😉
