C51: REENTRANT STACK NEEDED FOR REENTRANT LIBRARY FUNCTIONS?


Information in this article applies to:

  • C51 All Versions

QUESTION

I am using library functions such as memcpy and memcmp in my application. According to the manual, these library functions are reentrant. Does this mean that I have to set up a reentrant stack in the STARTUP.A51 module?

ANSWER

No, it is not necessary to set up a reentrant stack for these library functions. These functions are reentrant because they hold all local variables in registers and do not store them in memory.
