The SimReadRecordfunction reads a file from the SIM. This function is part of the SIM Manager API set that enables access to information stored on the SIM card.

Syntax 

HRESULT SimReadRecord (
  HSIM 
hSim,
  DWORD 
dwAddress,
  DWORD 
dwRecordType,
  DWORD 
dwIndex,
  LPBYTE 
lpData,
  DWORD 
dwBufferSize,
  LPDWORD 
lpdwBytesRead
);

Parameters

hSim

Points to a valid HSIM handle.

dwAddress

A unique ID specifying the name of the SIM record.

dwRecordType

A SIM_RECORDTYPE constant. See the Remarks section for a listing of all possible SIM_RECORDTYPEconstants.

dwIndex

Applies only to the SIM_RECORDTYPE_CYCLIC and SIM_RECORDTYPE_LINEAR constants; this parameter is ignored in any other case.

lpData

Data buffer.

dwBufferSize

Size of the data buffer.

lpdwBytesRead

Number of bytes read.

Return Value

HRESULTs are either S_OK for success, or one of the SIM_Eerror constants defined in the SIM Manager Error Constantstable.

Remarks

The following table contains a listing of all the SIM_RECORDTYPEconstants.

Constant Value Description

SIM_RECORDTYPE_UNKNOWN

0x00000000

An unknown record type.

SIM_RECORDTYPE_TRANSPARENT

0x00000001

A single variable-length record.

SIM_RECORDTYPE_CYCLIC

0x00000002

A cyclic set of records, each of the same length.

SIM_RECORDTYPE_LINEAR

0x00000003

A linear set of records, each of the same length.

SIM_RECORDTYPE_MASTER

0x00000004

Every SIM has a single master record, effectively the head node.

SIM_RECORDTYPE_DEDICATED

0x00000005

Effectively, a directory record that is a parent of other records.

The SIM record system contains several folders, some of which are for specific record types. Some records are stored at the root level, and must be accessed differently than those in folders. You are restricted to accessing records within the currently selected folder. To access records in folders other than the current folder, you must navigate through the folder structure first.

The SimReadRecordfunction can only be used to read the first 255 bytes from a transparent (binary) file.

Note:
This is a privileged API.
