STANDARD C LIBRARY HELPER FUNCTIONS
These functions are called by other functions in the standard C library and must be
modified for the target application. The corresponding object modules are distributed in
the

status
This is a helper function called by the exit() Standard C Library func-
tion.
As distributed, this function flushes stdout and terminates. The parame-
ter status is the same as that passed to the exit() standard C library
function.
_exit.c
Set the end of the process's data space.
None
int brk(void *endds);
endds
Returns ‘0’ if successful, ‘-1’ if not.
brk() is used to dynamically change the amount of space allocated for
the calling process's data segment. The change is made by resetting
the process's break value and allocating the appropriate amount of
space. The break value is the address of the first location beyond the
end of the data segment. The amount of allocated space increases as
the break value increases.
Newly allocated space is uninitialized.
This helper function is used by the Standard C Library function mal-
loc().
archive and the source code (for the compiler) is available in the

pointer to the end of the data segment
