[previous] 0309 [next] [U] Integral type is not large enough to hold a pointer value.
Explicitly undefined REFERENCE - ISO:C90-6.3.4 Cast Operators - Semantics

A pointer is being cast to an integral type but the type is too small to represent the value.

Perhaps it is necessary to use a larger integral type but this may simply be a problem which can be resolved by reconfiguring QAC. The size of pointer types as well as object types can be configured using the -size (-s) option (compiler personality).

By default, pointers to objects and pointers to functions are assumed to be represented in 32 bits. Under this configuration, message 0309 will be generated if a pointer is cast to an integral type which is configured in less than 32 bits.

For example: 


/*PRQA S 306,2017,3198,3199,3203,3205,3227,3408,3673 ++*/

extern void foo(int *pi)
{
    unsigned char  uc;
    unsigned short us;
    unsigned int   ui;
    unsigned long  ul;

    uc = (unsigned char )pi;                     /* Message 0309 */
    us = (unsigned short)pi;                     /* Message 0309 */
    ui = (unsigned int  )pi;                     /*              */
    ul = (unsigned long )pi;                     /*              */
}
