Convert char to const char

Using Arduino Programming Questions
#1

Hi,

I'm using an Ethernet shield and the TVOut Library to display any text data from any website. The TVOut requires a const char * to display text, but the Ethernet shield returns a regular char.Is there a way I can convert the regular char to a const char * ?

Thanks,

Michael

void f1 (char *p ) { char s[] = "Gorm"; const char *pc = s ; // pointer to constant pc [3] = ´g´; // error: pc points to constant pc = p; // ok char *const cp = s ; // constant pointer cp [3] = ´a´; // ok cp =p; / / error: cp is constant const char *const cpc = s ; // const pointer to const cpc [3] = ´a´; // error: cpc points to constant cpc = p ; // error: cpc is constant }

You can modify this way:

void g (const char *p ) { // can’t modify *p here } void h() { char *ptr="hello" ; // ptr can be modified g(ptr); // ... }
