问题描述
FILE * msgFile = fopen（" MessageFile.log"，" w"）;
.....
fprintf（msgFile ，OK，All Done.\ n;）

这是我的计划结束，但是它仍然是错误的。
任何想法？
FILE *msgFile = fopen("MessageFile.log", "w");
.....
fprintf(msgFile, "OK, All Done.\n");

Thats at the end of my program, and yet it still seg faults.
any Ideas?

你检查了fopen（）的返回值吗？尝试发布一个小的，完整的，可编辑的程序来展示有问题的行为。
Robert Gamble
Did you check the return value of fopen()? Try posting a small,
complete, compilable program that exhibits the problematic behavior.

您是否检查过fopen（）是否返回NULL？

如果你撒谎到编译器，它将报复。 - Henry Spencer
Did you check to see if fopen() returned NULL ?

If you lie to the compiler, it will get its revenge. -- Henry Spencer

鉴于您显然不愿意提供更多详细信息，如果可能是b $ b，则可以使用完整，可编译的程序来展示您的问题，
我们除了做出疯狂的猜测之外别无他法。正如其他人说的那样，在使用
相关指针之前，检查fopen是否确实已经成功。
Given your apparent reluctance to provide more details and, if
possible, a complete, compilable program that exhibits your problem,
there''s not much we can do other than make wild guesses. As others
have said, check whether fopen really does suceed, before using the
associated pointer.
