basic.%close.apdos

C Function/BASIC Program, Releases: AP/DOS

Closes an MS-DOS file.

Syntax

rc = %close(file.handle)

Description

closes an MS-DOS file specified by the 'file.handle' returned by a previous call to '%open()'.

For more information, refer to the MS-C library reference manual under CLOSE(). All MS-DOS files must be explicitly closed, since files are not automatically closed at program termination. Closing one of the system files (stdin, stdout, etc.) has unpredictable results.

Should an error condition arise within this C function, the 'system(0)' function contains the associated error message number.
