Description
The cc_GetBilling( ) function gets the call charge information associated with the
specified call. The billing information is in a NULL terminated ASCII string. The
information is retrieved from the network.

billing_buf: Pointer to the buffer where the billing string will be stored.
Use CC_BILLSIZE to define the buffer size.

Cautions
• Make sure the size of billing_buf is large enough to hold the string. The
maximum string is defined by CC_BILLSIZE.
• cc_GetBilling( ) may not function in all service-provider environments.
Check whether retrieving Vari-A-Bill billing information is an option with the
service provider.
• The cc_GetBilling( ) function is valid only after the call is terminated and
before the cc_ReleaseCall( ) function is called.
