C Library for C2000

Hi!

Does anybody know if the clib functions (like string manipulation functions or software floating point functions) are reentrant? Even if I know that I should not use these functions in interrupt service routines, sometimes it might be quite useful. May I do this?

Regards,

Some are, some are not, depending on the form of threading and the type of state. There are degrees of reentrancy. There is no published chart of reentrancy properties for the TI library functions, but they generally behave the same as they would from another vendor. That is, strtok is absolutely not reentrant, but strcpy is. See the following wiki entry for a starting point.
