Functions to handle initialization and allocation of all mysys & debug thread variables.
int my_errno | ( | ) |
Retrieve the MySQL thread-local storage variant of errno.
void my_thread_end | ( | void | ) |
Deallocate memory used by the thread for book-keeping.
void my_thread_global_end | ( | ) |
bool my_thread_global_init | ( | ) |
initialize thread environment
false | ok |
true | error |
void my_thread_global_reinit | ( | ) |
Re-initialize components initialized early with my_thread_global_init
.
Some mutexes were initialized before the instrumentation. Destroy + create them again, now that the instrumentation is in place. This is safe, since this function() is called before creating new threads, so the mutexes are not in use.
bool my_thread_init | ( | void | ) |
Allocate thread specific memory for the thread, used by mysys and dbug.
false | ok |
true | Fatal error; mysys/dbug functions can't be used |
bool my_thread_is_inited | ( | ) |
CODE_STATE ** my_thread_var_dbug | ( | ) |
my_thread_id my_thread_var_id | ( | ) |

void set_my_errno | ( | int | my_errno | ) |
Set the MySQL thread-local storage variant of errno.
