#include <nitro/os.h>u32 OS_GetResetParameter( void );
None.
The value of the reset parameter. This function returns 0 from the time that power is turned on until the OS_ResetSystem function is called.
Obtains the reset parameter value.
The reset parameter is the value that is provided by the parameter argument of the most recent function. This function returns 0 from the time that power is turned on until the OS_ResetSystemOS_ResetSystem function is called.
Example:
u32 n;
NitroMain()
{
:
n = OS_GetResetParameter();
OS_Printf( "%d\n", n );
:
OS_ResetSystem( n + 1 );
}
In the above example, 0 will be displayed first. Each reset after that will display 1, 2, 3 .... and so on.
The reset parameter is held in the 4-byte region that comes after HW_RESET_PARAMETER_BUF. The 4-byte region is placed in the system shared region and is not cleared by a reset. This function reads and returns the value in this region.
The OS_ResetSystem function can only be called when the system is in NITRO mode, so this function always returns 0 if called in TWL mode.
