values
On success, this function returns the status code LMX_SUCCESS.
On failure, this function returns an error code in the format described in Return codes.

Remarks
This function will send a message to the server from which a feature was checked out.
The length of the message sent to the server and the response can be up to LMX_MAX_LONG_STRING_LENGTH bytes.
In order for this function to succeed, the license server must have a function callback implemented. See lmxserverconf lmx_server_conf.c for details.
Example:
The following example shows a function that could be registered in lmxserverconf lmx_server_conf.c:
| Code Block | ||
|---|---|---|
| ||
/* The function parameters should be overwritten by the response back to the client. */ |
...
void LMX_CALLBACK ServerFunc(char *szMessage) |
...
{ char *szTest = "this is a simple response"; |
...
LmxLogprintf("server function called: %s", szMessage); |
...
/* Use the client message in some way ...*/ |
...
... |
...
... |
...
... |
...
/* Prepare response */ |
...
strcpy(szMessage, szTest); |
...
} |
The client can then invoke the function given above as follows:
| Code Block | ||
|---|---|---|
| ||
char szMyMessage[LMX_MAX_LONG_STRING_LENGTH+1]; |
...
char *szString = "This is my simple query"; |
...
int nLength; |
...
LMX_STATUS LmxStat; |
...
/* Specify a message to send (here we use a zero-terminated string, but any data could be used */ |
...
strcpy(szMyMessage, szString); |
...
LmxStat = LMX_ServerFunction(handle, "f1", szMyMessage); |
...
/* Now the query has been replaced with a response */ |
...
/* Print out the response since we know the server sent us a string */ |
...
printf("%s\n", szMyMessage); |
