rfio_chmod, rfio_fchmod - change access mode of a directory/file

[1m#include <sys/types.h>[0m
[1m#include "rfio_api.h"[0m

[1mint rfio_chmod (const char *[4m[22mpath[24m[1m, mode_t [4m[22mmode[24m[1m);[0m
[1mint rfio_fchmod (int [4m[22ms[24m[1m, mode_t [4m[22mmode[24m[1m);[0m

[1mrfio_chmod [22msets the access permission portion of the mode of a direc-
tory/file to the bit pattern in [4mmode.[0m

[1mrfio_fchmod [22mis identical to [1mrfio_chmod [22mbut works on the file descriptor
[4ms[24m returned by [1mrfio_open[22m.

[4mpath[24m specifies the logical pathname relative to the current directory
or the full pathname.

[4mmode[24m is constructed by OR'ing the bits defined in <[1msys/stat.h[22m> under
Unix or [1m"statbits.h" [22munder Windows/NT:

[1mS_IRUSR 0000400 [22mread by owner
[1mS_IWUSR 0000200 [22mwrite by owner
[1mS_IXUSR 0000100 [22mexecute/search by owner
[1mS_IRGRP 0000040 [22mread by group
[1mS_IWGRP 0000020 [22mwrite by group
[1mS_IXGRP 0000010 [22mexecute/search by group
[1mS_IROTH 0000004 [22mread by others
[1mS_IWOTH 0000002 [22mwrite by others
[1mS_IXOTH 0000001 [22mexecute/search by others

The effective user ID of the process must match the owner of the file
or be super-user. If a directory is writable and has the sticky bit
set, files/directories within that directory can be removed or renamed
only if:

the effective user ID of the requestor matches the owner ID of
the file or

the effective user ID of the requestor matches the owner ID of
the directory or

the file is writable by the requestor or

the requestor is super-user.

This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, [1mserrno [22mis set appropriately.

[1mEPERM [22mThe effective user ID does not match the owner of the file
and is not super-user.

[1mENOENT [22mThe named file/directory does not exist or is a null path-

[1mEBADF [4m[22ms[24m is not a valid file descriptor.

[1mEACCES [22mSearch permission is denied on a component of the [4mpath[0m
prefix or write permission on the file itself is denied.

[1mEFAULT [4m[22mpath[24m is a NULL pointer.

[1mENOTDIR [22mA component of [4mpath[24m prefix is not a directory.

[1mENAMETOOLONG [22mThe length of [4mpath[24m exceeds [1mCA_MAXPATHLEN [22mor the length of
a [4mpath[24m component exceeds [1mCA_MAXNAMELEN[22m.

[1mSENOSHOST [22mHost unknown.

[1mSENOSSERV [22mService unknown.

[1mSECOMERR [22mCommunication error.
