Accessing inside a structure via using a struct pointer to a struct pointer

[Awareness]

#include <stdio.h>

struct datastructure
{
char character;
};


void function(struct datastructure** ptr);


int main()
{
struct datastructure trial;
struct datastructure *structPtr;
structPtr=&trial;
structPtr->character='a';
function(&structPtr);
}


void function(struct datastructure** ptr)
{
*ptr->character='a';
printf("Ptr: %c",*ptr->character);
}

These codes give these errors:

error: request for member 'character' in '* ptr', which is of non-class type 'datastructure*'
error: request for member 'character' in '* ptr', which is of non-class type 'datastructure*'

these errors are related to

*ptr->character='a';
printf("Ptr: %c",*ptr->character);

I want to access character data inside the structure trial by a pointer to pointer ptrinside function function but I couldn't find a way to do this.

Problem is solved:

I should write:
(*ptr)->character='a'

instead of *ptr->character='a'

[coder777]

Try this: (*ptr)->character='a'; // Note ()

HINT : Operator -> has a higher precedence than the * operator.
