Socket APIs like recvfrom(), accept(), and getsockname() expect socklen_t*
arg, but tests were using int variables. This causes -Wpointer-sign
warnings on platforms where socklen_t is unsigned.
Change the variable type from int to socklen_t to resolve the warning and
ensure type safety across platforms.
warning fixed:
sctp_collision.c:62:70: warning: passing 'int *' to parameter of
type 'socklen_t *' (aka 'unsigned int *') converts between pointers to
integer types with different sign [-Wpointer-sign]
62 | ret = recvfrom(sd, buf, sizeof(buf),
0,
(struct sockaddr *)&daddr, &len);
| ^~~~
/usr/include/sys/socket.h:165:27: note: passing argument to
parameter '__addr_len' here
165 | socklen_t *__restrict __addr_len);
| ^
