Can't see anything wrong with the function itself (except that it's very
clumsy). So the memory corruption will be outside the function.
A better implementation would be to to the stripping in place and dodge
the two copies, and leave it more idiomatic and easier to read.
void stripLeadingSpacesInPlace(char *str) {
char *in, *out;
in = str;
out = str;
while (*in) {
if (!isspace(*in)) {
*out++ = *in++;
} else {
in++;
}
}
*out = '\0';
}
Yes I know the function name is probably too long, but I've been
programming Java for the past 5 months so I'm corrupted.
