Exceptions: Difference between revisions

=={{header|C}}==

The setjmp()/longjmp() functions in the C standard library header <setjmp.h> is typically used for exception handling.

===try-catch===

#include <setjmp.h>

enum { MY_EXCEPTION = 1 }; /* any non-zero number */

jmp_buf env;

void foo()

{

longjmp(env, MY_EXCEPTION); /* throw MY_EXCEPTION */

}

void call_foo()

{

switch (setjmp(env)) {

case 0: /* try */

foo();

break;

case MY_EXCEPTION: /* catch MY_EXCEPTION */

/* handle exceptions of type MY_EXCEPTION */

break;

default:

/* handle any type of exception not handled by above catches */

}

}
