Temporary PAM files in virtual memory (INCORE files)

If the file name "(INCORE)" is specified with the functions fopen/fopen64, freopen/freopen64 or open/open64, a temporary PAM file is created in virtual memory. This file "lives" only for the duration of a program run.

INCORE files must be opened for writing before they can be accessed for reading (cf. fopen/fopen64, freopen/freopen64, open/open64).

INCORE files are processed as binary files.
