L_LTANN_API L_INT L_AnnFileInfo(pszFile, pAnnFileInfo, uStructSize)

L_TCHAR *pszFile;	/* input file name to query */
pANNFILEINFO pAnnFileInfo;	/* pointer to a structure */
L_UINT uStructSize;	/* size in bytes, of the structure pointed to by pAnnFileInfo */

Gets information about the specified annotation file and fills the specified ANNFILEINFO structure with the information.

Parameter	Description
pszFile	Character string containing the name of the annotation input file.
pAnnFileInfo	Pointer to the ANNFILEINFO structure to be filled. For more information, refer to the ANNFILEINFO structure.
uStructSize	Size in bytes, of the structure pointed to by pAnnFileInfo, for versioning. Use sizeof(ANNFILEINFO).

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function can be used to find information about a LEAD annotation file.

To use this function, do the following:

1.	Declare a variable with the datatype of ANNFILEINFO.
2.	Fill in the nSize and nOffset fields of the ANNFILEINFO variable. The field nSize should contain the size of the ANNFILEINFO structure in bytes. The nOffset field should contain the byte location of the first byte of the annotation file.
3.	Declare and assign a character string variable for the annotation file name.
4.	Call the L_AnnFileInfo function, passing the file name and the address of the ANNFILEINFO variable as parameters.
5.	Get the image information from the fields described in the ANNFILEINFO structure.

Example

This example saves the annotation container as the first page of a multi-page annotation file. The format is specified by the 'uFormat' parameter. The container is flipped, and saved as the second page. The container is rotated, and saved as the third page. Information is displayed about the annotation file. The second page is deleted, and information is again displayed about the annotation file.
