#154851 - Real C is inherently reentrant Responding to: ???'s previous message |
One of the basic assumptions of Real 'C' is that functions are inherently reentrant (unless your specific coding makes them not).
Certainly with Keil (and, I suspect, with others) this is not the case on the 8051! Probably the biggest effects of this are on calling functions from main & interrupt code (and/or from different interrupt levels), and the use of Function Pointers... |
