getlogin_r(3) OSS Library Calls Reference Manual
• Link your application to:
/G/system/zdllnnn/zsecdll (32-bit applications)
or
/G/system/zdllnnn/ysecdll (64-bit applications) |
To use the Standard POSIX Threads library, you must:
• Include the spthread.h header file
• Link your application to the Standard POSIX Threads Library:
/G/system/sysnn/zsptsrl (G-series)
or
/G/system/zdllnnn/zsptdll (H-series or J-series)
• Compile your application using the #define _SPT_MODEL_ macro or an equivalent
compiler command option

RETURN VALUES
If the call completes successfully, the getlogin_r( ) function returns 0 (zero). Otherwise, an error
number is returned to indicate the error.
If this condition occurs, the getlogin_r( ) function returns the corresponding value:
[ENOMEM] There is insufficient user memory to complete the call.
[ERANGE] The value of the namesize parameter is smaller than the length of the string to be
returned, including the terminating null character.
ERRORS
No error values are returned. The getlogin_r( ) function does not set the errno variable.
