在win95,98机器上必须用leverl 50，也就是使用share_info_50结构。以下是详细说明，后附VC的源码，我已经调试通过。
struct share_info_50 {
char shi50_netname[LM20_NNLEN+1]; /* 共享名 */
unsigned char shi50_type; /* see below */
unsigned short shi50_flags; /* see below */
char FAR * shi50_remark; /* 共享描述 */
char FAR * shi50_path; /* 共享资源，必须大写 */
char shi50_rw_password[SHPWLEN+1]; /* 读写口令 */
char shi50_ro_password[SHPWLEN+1]; /* 只读口令 */
};

shi50_type的值：
#define STYPE_DISKTREE 0 /* 磁盘共享*/
#define STYPE_PRINTQ 1/* 打印机共享 */
#define STYPE_DEVICE 2
#define STYPE_IPC 3

shi50_flags的值：
#define SHI50F_RDONLY 0x0001
#define SHI50F_FULL 0x0002
#define SHI50F_DEPENDSON (SHI50F_RDONLY|SHI50F_FULL)
#define SHI50F_ACCESSMASK (SHI50F_RDONLY|SHI50F_FULL)
#define SHI50F_PERSIST 0x0100 /* 系统重启时重新建立该共享资源 */
#define SHI50F_SYSTEM 0x0200

以下是VC的源码：
#include <svrapi.h>
CString strNetName = "tmp";
CString strPasswdRW = "ddd";
CString strPasswdRO = "ddd";
CString strPath = "C:\\TMP"; // 一定要大写，否则出错NERR_UnknownDevDir
CString strRemark = "my tmp";

NET_API_STATUS nas;
share_info_50 si5;
si5.shi50_type = STYPE_DISKTREE;
si5.shi50_flags = SHI50F_FULL;
si5.shi50_path = (char*)LPCTSTR(strPath);
si5.shi50_remark = (char*)LPCTSTR(strRemark);
memset((void*)si5.shi50_netname, 0, SHPWLEN+1);
strncpy((char*)si5.shi50_netname, LPCTSTR(strNetName), strNetName.GetLength());
memset((void*)si5.shi50_rw_password, 0, SHPWLEN+1);
strncpy((char*)si5.shi50_rw_password, LPCTSTR(strPasswdRW), strPasswdRW.GetLength());
memset((void*)si5.shi50_ro_password, 0, SHPWLEN+1);
strncpy((char*)si5.shi50_ro_password, LPCTSTR(strPasswdRO), strPasswdRO.GetLength());

nas = NetShareAdd(NULL, 50, (char *)&si5, sizeof(share_info_50));

代码如下, :P

#include <stdio.h>
#include <windows.h>
#include <svrapi.h>

int main(int argc, char FAR * argv[])
{
short nLevel = 50;
struct share_info_50* pBuf = NULL;
unsigned short cbBuffer;
NET_API_STATUS nStatus;

if (argc != 3)
{
printf("Usage: %s ShareName SharePath\n", argv[0]);
exit(1);
}

cbBuffer = sizeof(struct share_info_50);
pBuf = malloc(cbBuffer);

if (pBuf == NULL)
printf("No memory\n");

strcpy(pBuf->shi50_netname, argv[1]);
pBuf->shi50_type = STYPE_DISKTREE;
pBuf->shi50_flags = SHI50F_FULL;
pBuf->shi50_remark = NULL;
pBuf->shi50_path = argv[2];
pBuf->shi50_rw_password[0] = '\0'; // No password
pBuf->shi50_ro_password[0] = '\0'; // No password

nStatus = NetShareAdd(NULL,
nLevel,
(char FAR *)pBuf,
cbBuffer);

if (pBuf != NULL)
free(pBuf);

return 0;
}
