standard c library for escaping a string

Question

Is there a standard C library function to escape C-strings?

For example, if I had the C string:

char example[] = \"first line\\nsecond line: \\\"inne

while(*src++)
{
  if(*src == '\\' || *src == '\"' || *src == '\'')
    *dest++ = '\\';

  *dest++ = *src++;
}
