1=pod 2 3=head1 NAME 4 5ERR_remove_thread_state, ERR_remove_state - free a thread's error queue 6 7=head1 SYNOPSIS 8 9 #include <openssl/err.h> 10 11 void ERR_remove_thread_state(const CRYPTO_THREADID *tid); 12 13Deprecated: 14 15 void ERR_remove_state(unsigned long pid); 16 17=head1 DESCRIPTION 18 19ERR_remove_thread_state() frees the error queue associated with thread B<tid>. 20If B<tid> == B<NULL>, the current thread will have its error queue removed. 21 22Since error queue data structures are allocated automatically for new 23threads, they must be freed when threads are terminated in order to 24avoid memory leaks. 25 26ERR_remove_state is deprecated and has been replaced by 27ERR_remove_thread_state. Since threads in OpenSSL are no longer identified 28by unsigned long values any argument to this function is ignored. Calling 29ERR_remove_state is equivalent to B<ERR_remove_thread_state(NULL)>. 30 31=head1 RETURN VALUE 32 33ERR_remove_thread_state and ERR_remove_state() return no value. 34 35=head1 SEE ALSO 36 37L<err(3)|err(3)> 38 39=head1 HISTORY 40 41ERR_remove_state() is available in all versions of SSLeay and OpenSSL. It 42was deprecated in OpenSSL 1.0.0 when ERR_remove_thread_state was introduced 43and thread IDs were introduced to identify threads instead of 'unsigned long'. 44 45=cut 46
