V528. Pointer is compared with 'zero' value. Probably meant: *ptr != zero.
This error occurs in two similar cases.
1) The analyzer found a potential error: a pointer to bool type is compared to false value. It is highly probable that the pointer dereferencing operation is missing. For example:
bool *pState;
...
if (pState != false)
...The '*' operator is missing in this code. As a result, we compare the pState pointer's value to the null pointer. This is the correct code:
bool *pState;
...
if (*pState != false)
...2) The analyzer found a potential error: a pointer to the char/wchar_t type is compared to value '\0' or L'\0'. It is highly probable that the pointer dereferencing operation is missing. For example:
char *cp;
...
if (cp != '\0')This is the correct code:
char *cp;
...
if (*cp != '\0')This diagnostic is classified as:
