MessageSet C Reference Documentation
MessageSet
Current Version: 10.1.0
Represents a collection of email message sequence numbers or UIDs on an IMAP server.
Create/Dispose
HCkMessageSet instance = CkMessageSet_Create(); // ... CkMessageSet_Dispose(instance);
Creates an instance of the HCkMessageSet object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.
Objects created by calling CkMessageSet_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkMessageSet_Dispose.
Properties
Count
The number of message UIDs (or sequence numbers) in this message set.
topHasUids
void CkMessageSet_putHasUids(HCkMessageSet cHandle, BOOL newVal);
If TRUE then the message set contains UIDs, otherwise it contains sequence numbers.
topLastMethodSuccess
void CkMessageSet_putLastMethodSuccess(HCkMessageSet cHandle, BOOL newVal);
Indicate whether the last method call succeeded or failed. A value of TRUE indicates success, a value of FALSE indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:
- Any method that returns a string.
- Any method returning a Chilkat object, binary bytes, or a date/time.
- Any method returning a standard boolean status value where success = TRUE and failure = FALSE.
- Any method returning an integer where failure is defined by a return value less than zero.
Note: Methods that do not fit the above requirements will always set this property equal to TRUE. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.
topUtf8
void CkMessageSet_putUtf8(HCkMessageSet cHandle, BOOL newVal);
When set to TRUE, all "const char *" arguments are interpreted as utf-8 strings. If set to FALSE (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to TRUE, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to FALSE, all "const char *" return values are ANSI strings.
topMethods
ContainsId
Returns TRUE if the msgId is contained in the message set.
topFromCompactString
Loads the message set from a compact-string representation. Here are some examples:
Non-Compact String | Compact String |
1,2,3,4,5 | 1:5 |
1,2,3,4,5,8,9,10 | 1:5,8:10 |
1,3,4,5,8,9,10 | 1,3:5,8:10 |
GetId
Returns the message ID of the Nth message in the set. (indexing begins at 0). Returns 0xFFFFFFFF if the index is out of range.
InsertId
Inserts a message ID into the set. If the ID already exists, a duplicate is not inserted.
topLoadTaskResult
Loads the message set from a completed asynchronous task.
Returns TRUE for success, FALSE for failure.
topRemoveId
Removes a message ID from the set.
topToCommaSeparatedStr
const char *CkMessageSet_toCommaSeparatedStr(HCkMessageSet cHandle);
Returns a string of comma-separated message IDs. (This is the non-compact string format.)
Returns TRUE for success, FALSE for failure.
topToCompactString
const char *CkMessageSet_toCompactString(HCkMessageSet cHandle);
Returns the set of message IDs represented as a compact string. Here are some examples:
Non-Compact String | Compact String |
1,2,3,4,5 | 1:5 |
1,2,3,4,5,8,9,10 | 1:5,8:10 |
1,3,4,5,8,9,10 | 1,3:5,8:10 |
Returns TRUE for success, FALSE for failure.
