Simple string allocation system, allowing for freeing all allocated strings in one go

strpool.c

#define STR_NEW( pool, str ) ( pool = memcpy( (char*) memcpy( malloc( ( str ? strlen( str ) : 0 ) + 1 + \
    sizeof( char* ) ), &pool, sizeof( char* ) ) + sizeof( char*), str ? str : "", ( str ? strlen( str ) : 0 ) + 1 ) )

#define STR_FREE( pool ) while( pool ) { char* STR_FREE_TMP = ( pool - sizeof( char* ) ); \
    pool = ( *(char**)STR_FREE_TMP ); free( STR_FREE_TMP ); }

//---------------------------

char* strpool = NULL;

char const* s1 = STR_NEW( strpool, "Test1" );
char const* s2 = STR_NEW( strpool, "Test2" );

STR_FREE( strpool );
