RTX5的动态内存管理模块使用问题

morning_enr6U

使用MDK建立的RTX5工程，#include "rtx_lib.h"  这个头文件是不是只有RTX5的OS组件才用的到，用户代码不需要使用这个头文件呢？
我在测试407工程中外部SRAM的动态内存分配时，用到：osRtxMemoryInit 函数，但是需要包含 "rtx_lib.h" 头文件，MDK工程报错说
找不到这个头文件，但是工程里面RTX5的组件都有包含这个头文件，他们却不报错，奇怪了！

供用户调用的是这些：

原来这些都在 cmsis_os2.h header file 里面。

/// Allocate a memory block from a Memory Pool.
/// \param[in]     mp_id         memory pool ID obtained by \ref osMemoryPoolNew.
/// \param[in]     timeout       \ref CMSIS_RTOS_TimeOutValue or 0 in case of no time-out.
/// \return address of the allocated memory block or NULL in case of no memory is available.
void *osMemoryPoolAlloc (osMemoryPoolId_t mp_id, uint32_t timeout);

/// Return an allocated memory block back to a Memory Pool.
/// \param[in]     mp_id         memory pool ID obtained by \ref osMemoryPoolNew.
/// \param[in]     block         address of the allocated memory block to be returned to the memory pool.
/// \return status code that indicates the execution status of the function.
osStatus_t osMemoryPoolFree (osMemoryPoolId_t mp_id, void *block);

/// Get maximum number of memory blocks in a Memory Pool.
/// \param[in]     mp_id         memory pool ID obtained by \ref osMemoryPoolNew.
/// \return maximum number of memory blocks.
uint32_t osMemoryPoolGetCapacity (osMemoryPoolId_t mp_id);

/// Get memory block size in a Memory Pool.
/// \param[in]     mp_id         memory pool ID obtained by \ref osMemoryPoolNew.
/// \return memory block size in bytes.
uint32_t osMemoryPoolGetBlockSize (osMemoryPoolId_t mp_id);
