Function otSrpClientBuffersAllocateService 

pub unsafe extern "C" fn otSrpClientBuffersAllocateService(
    aInstance: *mut otInstance,
) -> *mut otSrpClientBuffersServiceEntry

Allocates a new service entry from the pool.

The returned service entry instance will be initialized as follows:

• mService.mName will point to an allocated string buffer which can be retrieved using the function otSrpClientBuffersGetServiceEntryServiceNameString().
• mService.mInstanceName will point to an allocated string buffer which can be retrieved using the function otSrpClientBuffersGetServiceEntryInstanceNameString().
• mService.mSubTypeLabels points to an array that is returned from otSrpClientBuffersGetSubTypeLabelsArray().
• mService.mTxtEntries will point to mTxtEntry.
• mService.mNumTxtEntries will be set to one.
• Other mService fields (port, priority, weight) are set to zero.
• mTxtEntry.mKey is set to NULL (value is treated as already encoded).
• mTxtEntry.mValue will point to an allocated buffer which can be retrieved using the function otSrpClientBuffersGetServiceEntryTxtBuffer().
• mTxtEntry.mValueLength is set to zero.
• All related data/string buffers and arrays are cleared to all zero.
