I'm getting confused about stubs...


Hello everyone
? I am using newlib for the first time.The manual says I should write stubs
to implement the basic functions.What function should I write?take sbrk for
example,should I implement
caddr_t sbrk(int incr)
{ ...}
or
caddr_t _sbrk(int incr)
{...}
?I'm using Sourcery G++ for STM32 chips.
Any help would be greately appreciated.
