NAMEcuserid() — get character login name of the user SYNOPSIS#include <stdio.h> char *cuserid(char *s); Remarks:Because this function behaved differently in previous releases of HP-UX, and behaves differently on other systems, its use is not recommended. It is provided only for conformance to current industry standards, and is subject to withdrawal in future releases of HP-UX. For portability and security, application writers and maintainers should search their existing code and replace references to cuserid() with equivalent calls to getpwuid (getuid()), getpwuid (geteuid()), or getlogin(), depending on which user name is desired. DESCRIPTIONcuserid() generates a character-string representation of the user name corresponding to the effective user ID of the process. 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. For multi-thread applications, if s is a NULL pointer, the operation is not performed and a NULL pointer is returned. |
