ttyslot(3) Library Functions Manual ttyslot(3)NAMEttyslot - Finds the slot for the current user in the user accounting databaseLIBRARYStandard C Library (libc.so, libc.a)SYNOPSIS#include <stdlib.h> int ttyslot (void);STANDARDSInterfaces documented on this reference page conform to industry standards as follows: ttyslot(): XSH4.2 Refer to the standards(5) reference page for more information about industry standards and associated tags.DESCRIPTIONThe ttyslot() function returns the index of the current user's entry in the user accounting database. The current user's entry is an entry for which the utline member matches the name of a terminal device associated with any of the process' file descriptors 0, 1, or 2 (standard input, standard output, or error output). The index is an ordinal number representing the record number in the database of the current user's entry. The first entry in the database is represented by the return value 0 (zero).NOTESThe ttyslot() function is scheduled to be withdrawn in a future version of the X/Open CAE Specification. [Tru64 UNIX] When compiled in the X/Open UNIX environment, calls to the ttyslot() function are internally renamed by prepending _E to the function name. When you are debugging a module that includes the ttyslot() function and for which _XOPEN_SOURCE_EXTENDED has been defined, use _Ettyslot to refer to the ttyslot() call. See standards(5) for information on when the _XOPEN_SOURCE_EXTENDED macro is defined.RETURN VALUESUpon successful completion, the ttyslot() function returns the index of the current user's entry in the user accounting database. If an error is encountered while searching the database, or if none of the file descriptors 0, 1, or 2 is associated with a terminal device, -1 is returned. The following behavior does not conform to the current standards, and is supported only for backward compatibility. [Tru64 UNIX] In applications that are compiled in an environment that excludes the _XOPEN_SOURCE_EXTENDED standard definitions, the ttys- lot() function returns 0 (zero) on error.RELATED INFORMATIONFunctions: getutxent(3), ttyname(3) Standards: standards(5) delim off ttyslot(3)
