%SIZE returns the number of bytes occupied by the constant or field. The argument may be a literal, a named constant, a data structure, a data structure subfield, a field, an array or a table name. It cannot contain an expression, but some constant-valued built-in functions and constant...

好了截取了每次写入完之后的info memory我们该怎么计算平均每个 key 的占用内存空间呢? 简单来说就是: 对象内存 = 写入后内存 - 写入前内存 = sizeof(keys) +sizeof(values) 那么简单自然知道 sizeof(key) = [写入后内存 - 写入前内存 - sizeof(values)] / n 下面简单计算下每种输入的key占据内存。 10...
Notice that fgets is quite different from gets: not only fgets accepts a stream argument, but also allows to specify the maximum size of str and includes in the string any ending newline character. */ virtual char * MFGets( char * str, int num ) = 0; // FILE * fopen ( const ...

The size is always in bytes, even if the requested data is a Unicode string.On error, set to one of the two values: IMM_ERROR_NODATA, or IMM_ERROR_GENERAL. Returns Int32 If the method succeeds, it returns S_OK. If it fails, it returns an error c...
