DosDelete

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

DosDelete (FileName, Reserved)

• 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.

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
• 206 ERROR_FILENAME_EXCED_RANGE

Global file name characters are not permitted.

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

  #define INCL_DOSFILEMGR
 
  USHORT  rc = DosDelete(FileName, Reserved);
 
  PSZ              FileName;      /* File name path */
  ULONG            0;             /* Reserved (must be zero) */
 
  USHORT           rc;            /* return code */

This example deletes a file in the current directory named test.dat.

  #define INCL_DOSFILEMGR
 
  #define FILE_DELETE "test.dat"
  #define RESERVED 0L
 
  USHORT rc;
 
   rc = DosDelete(FILE_DELETE,    /* File path name */
                  RESERVED);      /* Reserved (must be zero) */

  EXTRN  DosDelete:FAR
  INCL_DOSFILEMGR     EQU 1
 
  PUSH@  ASCIIZ  FileName      ;Filename path name string
  PUSH   DWORD   0             ;Reserved (must be zero)
