Overview

endgrent terminates access to the group database. It is commonly used after getgrent or setgrent in scripts or programs that need to access group database information.

Syntax

endgrent()

Options/Flags

This command does not have any options or flags.

Examples

// Open the group database
setgrent();
// Close the group database
endgrent();

Common Issues

Error: Operation not permitted

This error can occur if the user does not have sufficient permissions to close the group database. Ensure that the user has the necessary permissions to perform this operation.

Integration

endgrent can be used in conjunction with getgrent and setgrent to manage group database access. For example, the following script iterates through all groups in the database:

#include <grp.h>

int main() {
  setgrent();
  struct group *group;
  while ((group = getgrent()) != NULL) {
    // Process group information
  }
  endgrent();
  return 0;
}
