DosSetFileMode

Bindings:  C, MASM 

This call changes the mode (attribute) of the specified file. 

 DosSetFileMode     (FileName, NewAttribute, Reserved) 
 

 FileName (PSZ) - input 
    Address of the file path name. 

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

 NewAttribute (USHORT) - input 
    File's new attribute. File attributes are defined as follows: 

    Bit       Description 
    15-6      Reserved and must be zero. 
    5         File archive 
    4         Subdirectory 
    3         Volume label 
    2         System file (excluded from normal directory searches) 
    1         Hidden file 
    0         Read only file 

   
    These bits may be set individually or in combination.  For example, an 
    attribute value of 0021H (bits 5 and 0 set to 1) indicates a read-only 
    file that should be archived. 

 Reserved (ULONG) - input 
    Reserved 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 
    108       ERROR_DRIVE_LOCKED 
    206       ERROR_FILENAME_EXCED_RANGE 
 
 Remarks 

 Attributes for Volume Label (0008H) and Subdirectory (0010H) cannot be 
 changed using DosSetFileMode. If these attributes are specified, 
 ERROR_INVALID_PARAMETER is returned. 

 DosQFileMode is used to query the current settings for file attributes. 
 Calling DosQFSInfo obtains volume label information. 

 Attributes of root directories cannot be changed using DosSetFileMode. If 
 these attributes are specified, ERROR_ACCESS_DENIED is returned.
