cuserid(3S)


cuserid -- get character login name of the user

Synopsis

   #include <stdio.h>
   

char *cuserid(char *s);

Description

cuserid generates a character-string representation of the login name that the owner of the current process is logged in under. If s is a NULL pointer, this representation is generated in an internal static area, the address of which is returned. Otherwise, s is assumed to point to an array of at least L_cuserid characters; the representation is left in this array. The constant L_cuserid is defined in the stdio.h header file.

Errors

If the login name cannot be found, cuserid returns a NULL pointer; if s is not a NULL pointer, a null character ``\0'' will be placed at s[0].
