环境：AIX V5.2
compile:IBM VAC enterprise V7.0
程序代码：
root@zhguowen_sv:/asmdev/asm#cat errlog_find.c
#include <stdio.h>
#include <fcntl.h>
#include <sys/errlog.h>
int mode=0;
unsigned int magic;
errlog_handle_t errlog_va;
errlog_handle_t *hdl=&errlog_va;
int begintime=0710000007,endtime=0727000007;
/*MMDDHHMMYY (month, day, hour, minute, and year).*/
main()
{

rc=errlog_open(NULL,mode,magic,hdl);
if (rc==0)
{
printf("\nopen errlog sucessful!\n" ;
}
else

}
extern int begintime, endtime;

errlog_match_t andtop;
errlog_match_t *p=&andtop;
int ret;

/* * Select begin and end times */
beginstamp.em_op = LE_OP_GT; /* Expression ¡¯A¡¯ */
beginstamp.em_field = LE_MATCH_TIMESTAMP;
beginstamp.em_intvalue=begintime;

endstamp.em_field = LE_MATCH_TIMESTAMP;
endstamp.em_intvalue=endtime;
andstamp.em_op = LE_OP_AND; /* ¡¯A¡¯ and ¡¯B¡¯ */
andstamp.em_left = &beginstamp;
andstamp.em_right = &endstamp; /* * Select the classes we¡¯re interested in. */

softclass.em_field = LE_MATCH_CLASS;
softclass.em_strvalue = "S";
orclass.em_op = LE_OP_OR; /* ¡¯C¡¯ or ¡¯D¡¯ */
orclass.em_left = &hardclass;
orclass.em_right = &softclass;
andtop.em_op = LE_OP_AND; /* (¡¯A¡¯ and ¡¯B¡¯ and (¡¯C¡¯ or ¡¯D¡¯ */
andtop.em_left = &andstamp;
andtop.em_right = &orclass;
int direction=LE_REVERSE;
rc=errlog_set_direction(hdl, direction);
if (rc==0)
{
printf("\ndirection errlog sucessful!\n";
}
else
{
printf("\ndirection errlog failed!\n";
}
ret = errlog_find_first(hdl,&andtop,&result);
if (ret==0)
{
printf("\nfind errlog sucessful!\n";
}
else
{
printf("\nfind errlog failed!\n";
}
if (LE_ERR_INVARG == ret)
printf("\n\n return LE_ERR_INVARG \n";
if (LE_ERR_NOMEM == ret)
printf("\n\n return LE_ERR_NOMEM \n";
if (LE_ERR_IO == ret)
printf("\n\n return LE_ERR_IO \n");
if (LE_ERR_DONE == ret)
printf("\n\n return LE_ERR_INVFILE \n");
}
执行结果：
root@zhguowen_sv:/asmdev/asm#xlc errlog_find.c /usr/lib/liberrlog.a
root@zhguowen_sv:/asmdev/asm#./a.out
open errlog sucessful!
direction errlog sucessful!
find errlog failed!
return LE_ERR_IO
root@zhguowen_sv:/asmdev/asm#
问题：
此段程序的大部门代码摘自《Technical Reference: Base Operating System and Extensions, Volume 1》，少部分由自己编写。关于errlog_open errlog_find_first API见此书P212页。
程序运行返回错误代码 LE_ERR_IO 书上解释是An i/o error occurred.
因资料有限，请教这样的错误应当如何解决？或者是否有其它相关资料可以查询？
多谢！
