pb如何调用带结构参数的动态库
用VB可以调用成功具体调用如下：
Function DSGetModemByPosition Lib "gprsdll.dll" (ByVal Index As Long, modeminfo As ModemInfoStruct) As Long
结构体为：
Public Type ModemInfoStruct
M_modemid As Long
M_phoneno(0 To 11) As Byte
M_dynip(0 To 3) As Byte
M_conn_time As Long
M_refresh_time As Long
End Type
用PB是这样写的，不知在哪儿有问题：
Function Long DSGetModemByPosition(Long Index,str_ModemInfoStruct modeminfo) LIBRARY "GPRSDLL.DLL"
结构体为：
str_ModemInfoStruct：
longm_modemid
bytem_phoneno
bytem_dynip
longm_conn_time
longm_refresh_time
为什么调用时取不到值？
[解决办法]
试下这个
str_ModemInfoStruct：
long m_modemid
character m_phoneno[12]
character m_dynip[4]
long m_conn_time
long m_refresh_time
[解决办法]
Function Long DSGetModemByPosition(Long Index,ref str_ModemInfoStruct modeminfo) LIBRARY "GPRSDLL.DLL"
加上ref
