2.1 Using RMS from RTL Routines

When you create a file using the DEC C RTL I/O functions and macros, you can supply values for many RMS file attributes, including:

• Allocation quantity

• Block size

• Default file extension

• Default file name

• File access context options

• File-processing options

• File-sharing options

• Multiblock count

• Multibuffer count

• Maximum record size

• Record attributes

• Record format

• Record-processing options

See the description of the creat function in the Reference Section for information on these values.

Other functions that allow you to set these values include open, fopen, and freopen.

For more information about RMS, see the DEC C User's Guide for OpenVMS Systems.
