switch

Used to control conditional operations. Control passes to the operation whose case statement matches the value of switch(expression).

switch ( variable ) 
{ 
    case const:
    statements...; 
    default: 
    statements...; 
} 

Example

The following example contains a switch statement that tests the value of rc. If rc's value is 1, then the transaction is deemed a success.

    int rc;
    lr_start_transaction ("deposit");

    // Server API call 

    rc = 1; // Place your own call here e.g., rc = bank_deposit (50);
    switch(rc) {
    case 1: lr_end_transaction ("deposit", LR_PASS);
        break;
    case 0: lr_end_transaction ("deposit", LR_PASS);
        break;
    case -1: lr_end_transaction ("deposit", LR_FAIL);
        break;
    }

Example: Output:
Action.c(5): Notify Transaction deposit started.
Action.c(12): Notify Transaction deposit ended with Pass status (Duration: 0.0200).
