Hi,

im getting "Bus Error" trying to read stdin into a char* variable. I just want to read whole stuff coming over stdin and put it first into a variable, then continue working on the variable.

My Code is as follows:

char* content;
char* c;
while( scanf( "%c", c)) {
 strcat( content, c);
}

fprintf( stdout, "Size: %d", strlen( content));

But somehow i always get "Bus error" returned by calling "cat test.txt | myapp", where "myapp" is the compiled code above.

My question is how do i read stdin until EOF into a variable? As you see in the code, i just want to print the size of input coming over stdin, in this case it should be equal to the size of the file "test.txt".

I thought just using scanf would be enough, maybe buffered way to read stdin?
