What errors ? Compilation/Runtime ?

Generally during runtime, if a system call fails, it sets the global
variable 'errno' with a error number (generally defined in errno.h)
Now if you want to see the error descriptions you can use a standard
function 'strerror( errno );' which returns a pointer to char
describing the latest error in a string equivalent form.
You could probably print the error like -

printf ("Error = %s\n", strerror(errno));

from the documentation for either the application or your compiler, or
your OS, depending on which is generating the errors.

(C doesn't mandate any specific error numbers or codes, this is
implementation specific)

perror() and a decent c manual would be a good start.
