How to remove first character from C-string?

Question

Can anyone please help me? I need to remove the first character from a char * in C.

For example, char * contents contains a \'\\n\'

Answer 1

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

Or, if the pointer can be modified:

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