Hex Mnemonic Description
0x207E ERPC All other RPC errors.
1. On pHILE+, CD-ROM, and MS-DOS formatted volumes, read_f() operations
are more efficient if bcount equals an integral multiple of the block size and the
L_ptr is positioned at a block boundary.
2. On pHILE+, CD-ROM, and MS-DOS formatted volumes, if the requested data
includes entire blocks or a contiguous sequence of blocks and if such blocks are
not already in the buffer cache, the pHILE+ file system manager reads these
blocks directly into the caller's buffer (without going through the buffer cache).
3. read_f() automatically positions the L_ptr for sequential read operations. If
random reads are necessary, use lseek_f() to reposition the L_ptr.
