每当我在 C 代码中调用 gethostbyname() 时,我都会收到此错误。

==7983== Invalid read of size 1
==7983==    at 0x412AB2C: ____strtoul_l_internal (strtol_l.c:298)
==7983==    by 0x412A46F: strtoul (strtol.c:110)
==7983==    by 0x41D427E: inet_aton (inet_addr.c:143)
==7983==    by 0x41D8FF3: __nss_hostname_digits_dots (digits_dots.c:144)
==7983==    by 0x41DD0F9: gethostbyname (getXXbyYY.c:109)
==7983==    by 0x804BE6F: connexion_function (in  ***************)
==7983==    by 0x8049A8F: main (in ***************)

有任何想法吗 ?谢谢,

它可能与gethostbyname不可重入并返回所有线程共享的对象有关。您可能应该使用getaddrinfofreeaddrinfo代替gethostbyname
