L_VOID pEXT_CALLBACK YourFunction(hNet, nError, nType, nLength, pUserData)
HDICOMNET hNet; |
/* handle to an existing DICOM network */ |
L_INT32 nError; |
/* error code */ |
L_CHAR *nType; |
/* pointer to a variable */ |
L_UINT32 nLength; |
/* length of data received */ |
L_VOID * pUserData; |
/* optional pointer to more parameters for the callback */ |
This function is called after data sent in non-secure mode is received. This function is available in the Medical Suite toolkits.
Parameter |
Description |
hNet |
Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function. |
nError |
Error code. Refer to Return Codes. |
nType |
Pointer to a variable to be updated with the type of data received. |
nLength |
The length of the received data, in bytes. |
pUserData |
Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter. |
Returns
None.
Comments
After data is received in a non-secure send process, this function is called. The data from pBuffer will be freed after this callback function returns.
If nError is DICOM_MEMORY_ERROR, an allocating memory error has occurred. In this case, pBuffer is NULL and nLength is 0.
