pdfLoadFileW
Load a PDF file from disk with a Unicode file name.
int pdfLoadFileW(PDFViewerHandle viewer, wchar_t *pdfFileName)
This function opens a PDF file,
pdfFileName, from disk,
and displays its first page.
pdfLoadFileW is identical to pdfLoadFile, except that
the file name is Unicode (wchar_t* instead
of char*).
The pdfLoadFile function returns pdfOk if
successful, otherwise an error code.
IMPORTANT: The PDF file on disk must not be deleted or modified
until after pdfCloseFile is called.
C:
if (pdfLoadFileW(viewer, L"c:\\test\\file.pdf") != pdfOk) {
/* error ... */
}
