# _CP_SADDR

_CP_SADDR returns a standard char* pointing
to the first character of the string buffer within a CPSTR structure.
Because _CP_SADDR is a macro, it can be used either
to the left or right side of an assignment operator.

## Syntax

```
char* _CP_SADDR(CPSTR* string)
```
Note: The char* that _CP_SADDR returns is not necessarily null-terminated.

## Example(s)

```
CPSTR * s = _CP_mkstr("hi");
_CP_SADDR(s)[1] = ’o’; /* replace 2nd character */
_CP_unix_env(); /* UNIX print environment */
_CP_TERM(s); /* null terminate */
printf("%s\n",_CP_SADDR(s));
```
