#define MOLFILE_BFACTOR 0x0004

B-factor data provided

◆ MOLFILE_BIGBUFSIZ

#define MOLFILE_BIGBUFSIZ 4096

◆ MOLFILE_BONDSSPECIAL

#define MOLFILE_BONDSSPECIAL 0x0100

Only non-standard bonds provided.

◆ MOLFILE_BUFSIZ

#define MOLFILE_BUFSIZ 81

Maximum string size macro.

maximum chars in string data

◆ MOLFILE_CHARGE

#define MOLFILE_CHARGE 0x0010

Atomic charge provided

◆ MOLFILE_CONVERTER_PLUGIN_TYPE

#define MOLFILE_CONVERTER_PLUGIN_TYPE "mol file converter"

File converter plugins use the same API but register under a different type so that regular file readers can have priority.

◆ MOLFILE_DIRECTIO_MAX_BLOCK_SIZE

#define MOLFILE_DIRECTIO_MAX_BLOCK_SIZE 4096

◆ MOLFILE_DIRECTIO_MIN_BLOCK_SIZE

#define MOLFILE_DIRECTIO_MIN_BLOCK_SIZE 4096

Hard-coded direct-I/O page size constants for use by both VMD and the plugins that want to use direct, unbuffered I/O for high performance with SSDs etc.

We use two constants to define the range of hardware page sizes that we can support, so that we can add support for larger 8KB or 16KB page sizes in the future as they become more prevalent in high-end storage systems.

At present, VMD uses a hard-coded 4KB page size to reduce memory fragmentation, but these constants will make it easier to enable the use of larger page sizes in the future if it becomes necessary.
