Coding Assumptions to Avoid

To avoid porting problems, examine code that assumes:

• "sizeof(int) == sizeof(void *)"

• "sizeof(int) == sizeof(long)"

• "sizeof(long) == 4"

• "sizeof(void *) == 4"

• "Implicitly Declared Functions"

• "Constants With the High-Order Bit Set"

• "Arithmetic with long Types" (including shifts involving mixed types and code that may overflow 32 bits)

sizeof(int) == sizeof(void *)

sizeof(int) == sizeof(long)

sizeof(long) == 4

sizeof(void *) == 4

Implicitly Declared Functions

Constants With the High-Order Bit Set

Arithmetic with long Types
