NOMBRE

SINOPSIS
       #define _GNU_SOURCE         /* Vea feature_test_macros(7) */
       #include <assert.h>

       void assert_perror(int errnum);

DESCRIPCION
       If the macro NDEBUG was defined at the moment <assert.h> was last
       included, the macro assert_perror()  generates no code, and hence does
       nothing at all.  Otherwise, the macro assert_perror()  prints an error
       message to standard error and terminates the program by calling
       abort(3)  if errnum is nonzero.  The message contains the filename,
       function name and line number of the macro call, and the output of
       strerror(errnum).

VALOR DEVUELTO

ERRORES
       The purpose of the assert macros is to help programmers find bugs in
       their programs, things that cannot happen unless there was a coding
       mistake.  However, with system or library calls the situation is rather
       different, and error returns can happen, and will happen, and should be
       tested for.  Not by an assert, where the test goes away when NDEBUG is
       defined, but by proper error handling code.  Never use this macro.
