MirOS Manual: vaccess(9)

VACCESS(9)                    BSD Kernel Manual                     VACCESS(9)

NAME

     vaccess - check access permissions based on vnode parameters

SYNOPSIS

     #include <sys/param.h>
     #include <sys/vnode.h>

     int
     vaccess(mode_t file_mode, uid_t uid, gid_t gid, mode_t acc_mode,
             struct ucred *cred);

DESCRIPTION

     The vaccess() function checks if the credentials described in cred are
     sufficient to perform the operation described by acc_mode, based on the
     file_mode, uid, and gid arguments. These arguments would typically be
     based on the vnode being accessed.

     file_mode is the current mode of the file that is having access checked.
     The uid and gid arguments are the user id and group id representing the
     owner of the file. acc_mode describes the operation desired. It should be
     one of VREAD, VWRITE, or VEXEC representing read, write, and execute,
     respectively.

RETURN VALUES

     vaccess() will return 0 on success, or a non-zero error value on failure.

ERRORS

     [EACCES]      Permission denied. An attempt was made to access a file in
                   a way forbidden by its file access permissions.
