The LEADFILECOMMENT structure contains information about a file comment field. A pointer to an array of this structure is obtained by the L_ReadFileComments function.
The type of this item comment. Valid values are:
|JPEG and LEAD File Comments|
|Tiff File Comments|
|Exif File Comments|
|Gif File Comments|
|Dicom File Comments|
|FlashPix File Comments|
|CMNT_LAST||Last defined number for comments. To clear all fields, you can use the type constant as a loop counter. The first constant is 0 and the last is CMNT_LAST.|
The number of bytes in the data items.
Byte offset into the ppData variables where the data for this item starts. To read the data for this item, you can use pItemData = (ppData + uDataOffset)
pLEADFILECOMMENT is a pointer to a LEADFILECOMMENT structure. Where the function parameter type is pLEADFILECOMMENT, you can declare a LEADFILECOMMENT variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pLEADFILECOMMENT variable is necessary only if your program requires a pointer.
Pass an address to pLEADFILECOMMENT to L_ReadFileComments to read all the comment fields stored in an image file. These functions will allocate this pointer with an array of pLEADFILECOMMENT structures, one for each item found. When you are done using the pLEADFILECOMMENT pointer, you must pass it to the L_FreeFileComments function to free the allocated memory.
