lchmod

LCHMOD(3)						   BSD Library Functions Manual 						 LCHMOD(3)

NAME

     lchmod -- change mode of file

SYNOPSIS

     #include <sys/stat.h>
     #include <unistd.h>

     int
     lchmod(const char *path, mode_t flags);

DESCRIPTION

     The function lchmod() sets the file permission bits of the file specified by the pathname path to mode.  See chmod(2) for the values of the
     flags.

     The lchmod() call is like chmod() except when the named file is a symbolic link, in which case lchmod() will change the flags of the link
     itself, rather than the file it points to.

NOTE

     Instead of being a system call, lchmod() is emulated using setattrlist(2).  Not all file systems support setattrlist(2).

RETURN VALUES

     Upon successful completion, a value of 0 is returned.  Otherwise, -1 is returned and the global variable errno is set to indicate the error.

ERRORS

     The lchmod() call may return the same errors as chmod(2) and setattrlist(2).

SEE ALSO

     chmod(2), setattrlist(2)
