DB_ENV->set_thread_id_string |
#include <db.h>int DB_ENV->set_thread_id_string(DB_ENV *dbenv, char *(*thread_id_string)(DB_ENV *dbenv, pid_t pid, db_threadid_t tid, char *buf));
Declare a function that formats a process ID and thread ID identifier pair for display into a caller-supplied buffer. The function must return a reference to the caller-specified buffer. The DB_ENV->set_thread_id_string method supports the DB_ENV->set_thread_id method.
The DB_ENV->set_thread_id_string method configures operations performed using the specified DB_ENV handle, not all operations performed on the underlying database environment.
The DB_ENV->set_thread_id_string method may be called at any time during the life of the application.
The DB_ENV->set_thread_id_string method returns a non-zero error value on failure and 0 on success.
If no thread_id_string function is specified, the default routine displays the identifier pair as "pid/tid", that is, the process ID represented as an unsigned integer value, a slash ('/') character, then the thread ID represented as an unsigned integer value.
The DB_ENV->set_thread_id_string method may fail and return one of the following non-zero errors:
