assert(3C)assert(3C)NAME
assert - verify program assertion
SYNOPSIS
#include <assert.h>
void assert(int expression);
The assert() macro inserts diagnostics into applications. When executed, if expression is FALSE (zero), assert() prints the error message
Assertion failed: expression, file xyz, line nnn
on the standard error output and aborts. In the error message, xyz is the name of the source file and nnn the source line number of the
assert() statement. These are respectively the values of the preprocessor macros __FILE__ and __LINE__.
Since assert() is implemented as a macro, the expression may not contain any string literals.
Compiling with the preprocessor option -DNDEBUG (see cc(1B)), or with the preprocessor control statement #define NDEBUG ahead of the
#include <assert.h> statement, will stop assertions from being compiled into the program.
Messages printed from this function are in the native language specified by the LC_MESSAGES locale category. See setlocale(3C).

assert.h, assert - verify program assertion
SYNOPSIS
#include <assert.h>
DESCRIPTION
The <assert.h> header defines the assert() macro. It refers to the macro NDEBUG which is not defined in the header. If NDEBUG is defined as
a macro name before the inclusion of this header, the assert() macro is defined simply as:
#define assert(ignore)((void) 0)
Otherwise, the macro behaves as described in assert(3C).
The assert() macro is redefined according to the current state of NDEBUG each time <assert.h> is included.
The assert() macro is implemented as a macro, not as a function. If the macro definition is suppressed in order to access an actual func-
tion, the behavior is undefined.

I have been doing this:
make xyz &> xyz.log &; tail -f xyz.log
The problem with this is that you never can ge sure when "make xyz" is done.
How can I pipe both stderr and stdout into tee so both stderr and stdout are copied both to the display and to the log file?
Thanks,
