ACCESS(2) ACCESS(2)
NAME
access - determine accessibility of file
SYNOPSIS
int access(char *name, int mode)
DESCRIPTION
Access evaluates the given file name for accessibility. If
mode&4 is nonzero, read permission is expected; if mode&2,
write permission; if mode&1, execute permission. If
mode==0, the file merely need exist. In any case all direc-
tories leading to the file must permit searches. Zero is
returned if the desired access is permitted, -1 if not.
Only access bits are checked. A directory may be announced
as writable by access, but an attempt to open it for writing
will fail (although files may be created there); a file may
look executable, but exec(2) will fail unless it is in
proper format.
