<<unix环境高级编>>程整本书的例子都有ourhdr.h头文件啊,你们帮帮我,要不我学不下去啊 ,,,怎么办 ?
后面的附录有ourhdr.h，兄弟不想敲字我这有:p ，因为我敲过了- /* Our own header, to be included *after* all standard system headers */

另外还有一个错误处理文件，你可以把它先编译出来，比如我把它命名为myerror.c：
- #include <errno.h> /* for definition of errno */
- #include <stdarg.h> /* ANSI C header file */
- #include "ourhdr.h"
-
- static void err_doit(int, const char *, va_list);
- char *pname = NULL; /* caller can set this from argv[0] */
-
- /* Nonfatal error related to a system call.
- Print a message and return */
-
- void
- err_ret(const char *fmt, ...)
- {
- va_list ap;
- va_start(ap, fmt);
- err_doit(1, fmt, ap);
- va_end(ap);
- return;
- }
-
- /* Fatal error related to a system call.
- Print a message and terminate. */
-
- void
- err_sys(const char *fmt, ...)
- {
- va_list ap;
- va_start(ap, fmt);
- err_doit(1, fmt, ap);
- va_end(ap);
- exit(1);
- }
-
- /* Fatal error related to a system call.
- Print a message and terminate. */
-
- void
- err_dump(const char *fmt, ...)
- {
- va_list ap;
-
- va_start(ap, fmt);
- err_doit(1, fmt, ap);
- va_end(ap);
- abort(); /* dump core and terminate */
- exit(1); /* shouldn't get here */
- }
-
- /* Nonfatal error unrelated to a system call.
- Print a message and return. */
-
- void
- err_msg(const char *fmt, ...)
- {
- va_list ap;
-
- va_stat(ap, fmt);
- err_doit(0, fmt, ap);
- va_end(ap);
- return;
- }
-
- /* Fatal error unrelated to a system call.
- Print a message and terminate. */
-
- void
- err_quit(const char *fmt, ...)
- {
- va_list ap;
- va_start(ap, fmt);
- err_doit(0, fmt, ap);
- va_end(ap);
- exit(1);
- }
-
- /* Print a message and return to caller.
- Caller specifies "errnoflag". */
-
- static void
- err_doit(int errnoflag, const char *fmt, va_list ap)
- {
- int errno_save;
- char buf[MAXLINE];
-
- errno_save = errno; /* value caller might want printed */
- vsprintf(buf, fmt, ap);
- if (errnoflag)
- sprintf (buf+strlen(buf), ": %s", strerror (errno_save));
- strcat (buf, "\n");
- fflush(stdout); /* in case stdout and stderr are the same */
- fputs(buf, stderr);
- fflush(NULL); /* flushes all stdio output streams */
- return;
- }
用gcc -c myerror.c编译得到myerror.o |
