9.0.0

SYNOPSIS
int _PxHndcall(PxHndcallFunction_t function, void *arg);
ARGUMENTS






function




Function to be called in supervisor mode


















arg




Argument as a void pointer

















DESCRIPTION










_PxHndcall calls the passed function handler with its argument arg in supervisor mode. Since the function is executed in the context of the calling task using the task stack, the function can only access data of the task context.



























USAGE








#include "pxdef.h"

typedef struct {
    PxUInt32_t interruptNumber;
    PxUInt32_t reloadValue;
} initializeStmTimerArgs_t;

int InitializeStmTimer(void *arg){
    initializeStmTimerArgs_t *argStruct = (initializeStmTimerArgs_t *) arg;

    PxUInt32_t interruptNumber = argStruct->interruptNumber;
    PxUInt32_t reloadValue = argStruct->reloadValue;
    ...

}

initializeStmTimerArgs_t args = {
    .interruptNumber = DELAY_INTERRUPT,
    .reloadValue = STM_RELOAD
};

int retval = _PxHndcall(InitializeStmTimer, &args);
