two exiting points in void function?

[L. Westmeier]

Is there a way to have to exiting point in a void function? I don't want
to exit the program but just this function.

Any answers appreciated.

#include <stdio.h>

void foo(int e)
{
if (e == 0) {
return;
}

printf("didn't exit early, e == %d\n", e);
}

Use return;

Its good practice to only have one return point from a function. Since
you didn't know about "return;", I'm guessing you're new to C so you may
want to post a small, compilable code sample to get feedback on whether
or not you're approaching this the right way.

Its bad practice to only have one return point from a function as the
single return far too often results in a plurality of status flags and
nested if-statements, all needed to go from the wanted return point to
the mandated return point.

Rules demanding "no goto" are often found where rules demanding
"only one return point" are found. These rules leads to the plurality
of status flags and nested if-statements, often combined with a
nice selection of bugs.

#include <stdio.h>

void foo(int e)
{
if (e == 0) {
return;
}

printf("didn't exit early, e == %d\n", e);
}

#include <stdio.h>

void foo(int e)
{
if (e != 0)
printf("didn't exit early, e == %d\n", e);
}

Same result, single return point.

[cut] void foo(int e)
{
if (e != 0)
printf("didn't exit early, e == %d\n", e);
}

Same result, single return point.

Not very useful for demonstrating the possibility of multiple
exit points though...
