cuserid - get character login name of the user
char *cuserid(char *s);
The cuserid() function generates a character-string
representation of the login name under which the owner of
the current process is logged in. If s is a null pointer,
this representation is generated in an internal static area
whose address is returned. Otherwise, s is assumed to point
to an array of at least L_cuserid characters; the represen-
tation is left in this array. The constant L_cuserid is
defined in the <stdio.h> header.
In multithreaded applications, the caller must always supply
an array s for the return value.
If the login name cannot be found, cuserid() returns a null
pointer. If s is not a null pointer, the null character
`\0' will be placed at s.
