L_INT LNITFFile::Create()

L_TCHAR * pszFileName;

/* file name */

Creates an empty NITF file or parses an existing NITF file.

Parameter

Description

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

The LNITFFile::Create must be called before calling any other LNITFFile::XXX 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 LNITFFile::SaveFile function.

When the class object is no longer needed, call the LNITFFile::Destroy function. For every call to LNITFFile::Create there must be a call to LNITFFile::Destroy.
