How to remove first character from C-string?

if (contents[0] == '\n') 
    memmove(contents, contents+1, strlen(contents));

Or, if the pointer can be modified:

if (contents[0] == '\n') contents++;

char* contents_chopped = contents + 1;

This will result in contents_chopped pointing to the same string, except the first char will be the next after \n

Also, this method is faster.
