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); | ^
