Table 3: Summary of cc Functions
access(filename, [mode])
returns true if the access mode of filename is the same as the supplied mode. The mode
should be passed as a string composed of the characters r, w, x, or f (for read, write,
execute, or file existence). If no mode is supplied, f is assumed.
access("temp.af9","f") -- checks if temp.af9 exists
access("temp.af9","rw") -- checks for read/write
permission on temp.af9
If the base operating system allows, mode can be passed as a number. This is non-portable, so
you should use a string representation.
cd(pathname)
changes the current directory to the value of pathname.
cinclude(filename)
includes the specified file. No path search is performed. If filename is not an absolute path
name, the current directory is searched. If the file does not exist, this function returns 0;
otherwise, it returns 1.
exec(expression {, expression})
is similar to the exec statement. The value of an exec expression is the exit status of the
last command executed. This is an integer.
filepath(expression)
returns a vector whose components are the strings corresponding to the path name
components of the string expression. The built-in variable DIRSEPSTR is used to determine
