NAME
cuserid() - get character login name of the user
SYNOPSIS
Remarks:
Because this function behaved differently in previous releases of HP-UX, and behaves differently on other systems, its use is not recom-
mended. 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 with equiva-
lent calls to or depending on which user name is desired.
DESCRIPTION
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 characters; the representation is left in this array. The constant is defined in the header file.
For multi-thread applications, if s is a NULL pointer, the operation is not performed and a NULL pointer is returned.
DIAGNOSTICS
If the login name cannot be found, returns a NULL pointer; if s is not a NULL pointer, a null character is placed at s[0].
WARNINGS
Obsolescent Interfaces
is to be obsoleted at a future date.
