DosDelete

This call removes a directory entry associated with a file name.

Syntax
DosDelete (FileName, Reserved)
Parameters
  • FileName (PSZ) - input : Address of the name of the file to be deleted.

DosQSysInfo is called by an application during initialization to determine the maximum path length allowed by OS/2.

  • Reserved (ULONG) - input : Reserved and must be set to zero.
Return Code
rc (USHORT) - return

Return code descriptions are:

  • 0 NO_ERROR
  • 2 ERROR_FILE_NOT_FOUND
  • 3 ERROR_PATH_NOT_FOUND
  • 5 ERROR_ACCESS_DENIED
  • 26 ERROR_NOT_DOS_DISK
  • 32 ERROR_SHARING_VIOLATION
  • 36 ERROR_SHARING_BUFFER_EXCEEDED
  • 87 ERROR_INVALID_PARAMETER

A file whose read-only attribute is set cannot be deleted. To change the setting of the read-only bit, call DosSetFileMode.

Example Code

C Binding

#define INCL_DOSFILEMGR

USHORT  rc = DosDelete(FileName, Reserved);

PSZ              FileName;      /* File name path */
ULONG            0;             /* Reserved (must be zero) */

USHORT           rc;            /* return code */

USHORT rc;

 rc = DosDelete(FILE_DELETE,    /* File path name */
                RESERVED);      /* Reserved (must be zero) */
