#include <nitro/os.h>void OS_InitStatistics( void* statBuf, u32 size );
| statBuf | Function cost statistics buffer |
| size | Size of the function cost statistics buffer |
None.
This function initializes the function cost statistics buffer.
To enable this function, at link time you must include libos.FUNCTIONCOST.a (in the thumb version libos.FUNCTIONCOST.thumb.a). To do this, specify NITRO_PROFILE_TYPE=FUNCTIONCOST as a make option. You may also write it in the makefile. However, in the final ROM version (FINALROM) library, it will not do anything.
Header information for (the number of bytes in sizeof(OSFunctionCostStatisticsInfo) - sizeof(OSFunctionCostStatistics) which includes the buffer's end position, the currently used pointer, etc) is stored in the front of the buffer buf.
Use OS_CalcStatistics() or OS_CalcThreadStatistics() to accumulate the contents from a function cost calculation buffer into the function cost statistics buffer. Then use OS_DumpStatistics() to display the contents. You can accumulate the contents of multiple function cost calculation buffers into one function cost statistics buffer.
