Hi ,
I am currently using ndk_2_24_03_35 and have a question about a couple of structures defined in socketndk.h.
/* AF_INET family (IPv4) Socket address data structure. */
struct sockaddr_in {
UINT8 sin_family; /* address family */
UINT16 sin_port; /* port */
struct in_addr sin_addr;
INT8 sin_zero[8]; /* fixed length address value */
};
/* Generic Socket address storage data structure. */
struct sockaddr {
UINT8 sa_family; /* address family */
char sa_data[14]; /* socket data */
};
These structures seem to be overlayed and interchanged within the stack code.
My compiler pads out structure sockaddr_in to avoid having member sin_port on an odd boundary making a size of 16 bytes compare to the size of socaddr
which is 15 bytes?
Within function NDK_recvfrom() if the sizeof socaddr (15 bytes) is passed in as parameter int *plen then the following check fails:-
/* Validate Sizes and Pointers */
if (pName && (!plen || (pName->sa_family == AF_INET && *plen < sizeof(SA_IN)) where SA_IN is struct sockaddr_in and *plen is the length of struct sockaddr.
Thanks in advance
Brian
