Comments
To use this function:
Declare a variable of type L_SIZE_T and pass the address of the variable as the puLen parameter
Pass NULL for the pText parameter
The length will be returned in the variable *puLen
Allocate a buffer of *puLen + 1
Call the function again passing the address of the buffer for pText
The text of the annotation object is returned in the buffer
Note: The text of the ruler object (which can be retrieved through L_AnnGetText) is the length + unit abbrev. The distance is reset every time the object is changed.
L_AnnGetText can be used to retreive the text from a Rich Text annotation object (ANNOBJECT_RTF). However, no formatting information will be preserved. To retrieve the text with formatting, see L_AnnGetTextRTF.
