Flexible array members
| |||
| Home > Language Extensions > Flexible array members | |||
The last member of a struct can have an incomplete array type. The last member must not be the only member of the struct, otherwise the struct is zero in size.
Example
typedef struct
{
int len;
char p[]; // incomplete array type, for use in a malloc’d data structure
} str;
