L_LTNTF_API L_INT L_NITFCreate(phNitf, pszFileName)

pHNITF phNitf;	/* pointer to a NITF file handle */
L_TCHAR * pszFileName;	/* file name */

Creates an empty NITF file or parses an existing NITF file. This function is available in the Document Toolkit.

Parameter	Description
phNitf	Pointer to a NITF file handle.
pszFileName	Character string that contains the name of the NITF file to be parsed.

Returns

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

Comments

L_NITFCreate must be called before calling any other L_NITFXXX functions.

To create an empty NITF file, pass the pszFileName parameter as NULL.

To parse an existing NITF file, pass a valid file name to the pszFileName parameter.

To save the created NITF file, call the L_NITFSaveFile function.

When the NITF file handle is no longer needed, it should be freed by calling L_NITFDestroy function. For every call to L_NITFCreate there must be a call to L_NITFDestroy.
