xpdfSpliceOpenOutputMem
Open an output PDF file, in memory.
XpdfSpliceOutputHandle xpdfSpliceOpenOutputMem(const char *fileNameData, int fileNameDataLen,
double pdfVersion)
This function opens an output PDF file that will be buffered in
memory.
fileNameDataLen bytes from fileNameData will
be used only when generating the file ID for encryption. If no file
name information is available, pass NULL for fileNameData
and 0 for fileNameDataLen.
The xpdfSpliceOpenOutputMem function returns an
XpdfSpliceOutputHandle if successful, and otherwise
returns NULL.
The PDF version in the output file will be set to
pdfVersion. XpdfSplice does not check that the content
conforms to the specified version. Typically, it should be set to the
highest version used in any of your input files.
The xpdfSpliceCloseOutputMem must be used to retrieve the memory
buffer.

XpdfSpliceOutputHandle out;
char *pdfData;
int pdfDataLength;
out = xpdfSpliceOpenOutputMem("test123.pdf", 11, 1.6);
if (!out) {
/* handle the error */
}
...
pdfData = xpdfSpliceCloseOutputMem(out, &pdfDataLength);
/* ... use pdfDataLength bytes at pdfData ... */
xpdfSpliceFreeMemory(pdfData);
