Hello
Is there any way to cast a volatile void pointer to e.g. a char pointer,
without getting a warning from gcc ?
Here is the warning:
pci.c:665: warning: cast discards qualifiers from pointer target type
example code:
extern int
pci_copyrom(volatile void * p)
{
unsigned char * romp;
romp = (unsigned char *) p;
thanks in advance
josef

Hi Josef,
Try either adding the volatile qualifier to romp, or removing the volatile
qualifier from p.
HTH,
