The LMX_Checkin function will return the licenses for a single checked in feature or all checked in features.

Prototype 

LMX_STATUS LMX_Checkin
(
   LMX_HANDLE LmxHandle,
   const char *szFeatureName,
   int nCount
);

Parameters

LmxHandle
[in/out] LM-X handle.

szFeatureName
[in] Feature name. Use parameter LMX_ALL_FEATURES to check in all features.

nCount
[in] Number of licenses to check in.

Use parameter LMX_ALL_LICENSES to check in all licenses.

Return 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

If all licenses are returned to a license server, the licensing system will also ensure that the network connection is closed.

Using LMX_ALL_FEATURES with borrow early return is not supported. Instead, check in the features individually.

Example

The following example returns a license for feature "f2" to a license server.

#include <lmx.h>
#include <stdio.h>

LMX_HANDLE h;

int main() 
{
  exit_on_error(LMX_Init(&h));
  exit_on_error(LMX_Checkin(h, "f2", 1));
  return 0;
}

The example below shows initializing LM-X and an attempt to check out a license, after which it displays information about the license including the time remaining to expiration and it tries to check in the license.

#include <lmx.h>
#include <stdio.h>

LMX_HANDLE h;

int main() 
{
  exit_on_error(LMX_Init(&h));
  printf("LM-X client handle successfully initialized: %p\n",h);
  
  exit_on_error(LMX_Checkout(h, "f2", 1, 0, 1));
  printf("Get a license.\n");

  LMX_FEATURE_INFO FI;
  exit_on_error(LMX_GetFeatureInfo(h, "f2", &FI));

  printf("FeatureName : %s\n", FI.szFeatureName);
  printf("VendorName : %s\n", FI.szVendorName);
  int nTimeLeft;
  nTimeLeft = LMX_GetExpireTime(h, "f2");
  if (nTimeLeft == -2)
    printf("This feature does not expire\n");
  else if (nTimeLeft == -1)
    printf("This feature is expired\n");
  else
    printf("Hours left for this feature: %d\n", nTimeLeft);

  exit_on_error(LMX_Checkin(h, "f2", 1));
  printf("License returned.\n");

  LMX_Free(h);
  return 0;
}
