vuPOP3Size()

Clarion prototype

Prototype: vuPOP3Size(LONG InMessageNumber), LONG, PROC, PASCAL, RAW, NAME(‘vuPOP3Size’)

Purpose

Returns the size (in bytes) of the specified message in the active POP3 session.

Parameters

| Parameter | Type | Description | |—|—|—| | InMessageNumber | LONG | 1-based POP3 message number. |

Return value / error codes

• 0: Message size in bytes.

• 0: No size available (for example, message not found or no active message list).
• < 0: Error code from POP3 session operations.

Example (Clarion)

msgNo   LONG
sizeB   LONG

msgNo = 1
sizeB = vuPOP3Size(msgNo)
IF sizeB > 0
  MESSAGE('POP3 message #1 size: ' & sizeB & ' bytes')
ELSE
  MESSAGE('vuPOP3Size returned: ' & sizeB)
END

Notes

• Use vuPOP3Count() first to validate message-number range.
• This call expects a connected POP3 session (vuPOP3Connect()).
