[previous] 1031 [next] [C99] Initializer for 'struct', 'union' or array type is not a constant expression.
ISO C99 Language features REFERENCE - ISO:C90-6.5.7 Initialization - Constraints

An array, struct or union with automatic storage duration is being initialized with an initializer which is not a constant expression. This is not permitted in ISO:C90, but it IS allowed in ISO:C99.

For example: 


/*PRQA S 2017,2213,2216,3120,3132,3199,3205,3227,3408,3604,3674 ++*/

struct ST {int a; int b;};

extern void foo(int p1, int p2, int p3)
{
    int var = p1;                         /* Scalar object - OK */

    int buf1[] = {1, 2, 3};

    int buf2[3]= {p1, p2, p3};            /* Message 1031 */

    struct ST sx = {p1, p2};              /* Message 1031 */
}
