SimReadRecord
The SimReadRecord function 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.
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_RECORDTYPE constants. - 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 Values
HRESULTs are either S_OK for success, or one of the SIM_E error constants defined in the SIM Manager Error Constants table.
Remarks
The following table contains a listing of all the SIM_RECORDTYPE constants.
| 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 SimReadRecord function can only be used to read the first 255 bytes from a transparent (binary) file.
Note This is a privileged API.
