integral constant expression

[Keith]

I receive compiler error messge: "integral constant expression expected"
for:

somefunc(char *bar)
{
char foo[2*strlen(bar)];
}
Is there any way around this? I am using SunWorkStop 5.0.
Thanks

That's called a variable length array [VLA] and you need an ISO C [c99]
compiler to handle that.

Short of that you may want to look into alloca [not portable] or malloc
[portable].

#include <stdlib.h>

somefunc(char *bar)
{
char *foo = malloc (2 * strlen(bar));
/* + 1 if you need room for the final 0. */

if (foo != NULL)
{
/* use it ... */
/* ... and when finished : */
free (foo);
}
}

Yeah: Use malloc().
