endttyent - Linux

Overview

endttyent is a Linux command that deallocates all memory and resources associated with a terminals database. It’s typically used in conjunction with other utility commands that require access to terminal-related information.

Syntax

endttyent()

Options/Flags

• None

Examples

Deallocate the terminals database:

#include <stdio.h>
#include <stdlib.h>
#include <utmp.h>

int main() {
    printf("Terminals database size: %d bytes\n", sizeof(struct utmp));
    endttyent();
    printf("Terminals database deallocated.\n");
    return 0;
}

Common Issues

• Segmentation fault: Occurs when accessing the terminals database after it has been deallocated. To avoid this, ensure you call endttyent() before accessing the database.

• getttyent(): Get the next entry from the terminals database.
• setutent(): Open the terminals database.
• utmpname(): Set the name of the terminals database.
