I have an enum declared as;
typedef enum { NORMAL = 0, EXTENDED }CyclicPrefixType_t; CyclicPrefixType_t cpType; I need a function that takes this as an argument :
fun (CyclicPrefixType_t cpType) ; func declaration is :
void fun(CyclicPrefixType_t cpType); Please help. I don't think it is correct.
Thanks

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum. Show activity on this post. Show activity on this post. First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions .
enum State {Working = 1, Failed = 0}; The keyword 'enum' is used to declare new enumeration types in C and C++. Following is an example of enum declaration. // The name of enumeration is "flag" and the constant // are the values of the flag.
You can use the operator & ( bitwise and ) and ( | bitwise or ) and use each bit as a bool. Remind that a enum behaves as a int. For example, if the user has pressed the keys W and S. Show activity on this post.
Yes. In C enum types are just int s under the covers. Typecast them to whatever you want. enums are not always ints in C.
That's pretty much exactly how you do it:
#include <stdio.h> typedef enum { NORMAL = 31414, EXTENDED } CyclicPrefixType_t; void func (CyclicPrefixType_t x) { printf ("%d\n", x); } int main (void) { CyclicPrefixType_t cpType = EXTENDED; func (cpType); return 0; } This outputs the value of EXTENDED (31415 in this case) as expected.

The following also works, FWIW (which confuses slightly...)
#include <stdio.h> enum CyclicPrefixType_t { NORMAL = 31414, EXTENDED }; void func (enum CyclicPrefixType_t x) { printf ("%d\n", x); } int main (void) { enum CyclicPrefixType_t cpType = EXTENDED; func (cpType); return 0; } Apparently it's a legacy C thing.
