Posted on November 21, 2008 at 07:22Hi all,
I have a one question about the INDIRECT access in this function. As you can find for example in:
http://www.cplusplus.com/reference/clibrary/cstdarg/va_start.html ''A function that executes va_start, shall also execute va_end before it returns.''
But in the library function from ST there are no such calling. Is it a problem? Can it cause memory leaks or somethimg bad else? Please do not propose to use the new library since the project my almost finished... :)
I list the part code from library:
FlagStatus I2C_FlagStatus (I2C_TypeDef *I2Cx, RegisterAccess Access, I2C_Flags Flag, ...)
{
u32 Tmp=0;
if (Access == DIRECT)
/* Store in Tmp variable the register where is located the flag */
Tmp = I2C_GetStatus(I2Cx)&Flag;
else
{
va_list list;
/* Get the fourth register */
va_start(list,Flag);
Tmp = va_arg(list,u32);
Tmp&=Flag;
}
/* Return the Flag NewState */
return Tmp != 0 ? SET : RESET;
}
