ERR_LOAD_CRYPTO_STRINGS(3)                            Library Functions Manual

NAME
     ERR_load_crypto_strings, ERR_free_strings, SSL_load_error_strings - load
     and free OpenSSL error strings

SYNOPSIS
     #include <openssl/err.h>

     void
     ERR_load_crypto_strings(void);

     void
     ERR_free_strings(void);

     #include <openssl/ssl.h>

     void
     SSL_load_error_strings(void);

DESCRIPTION
     These functions are deprecated.  It is never useful for any application
     program to call any of them explicitly.  The library automatically calls
     them internally whenever needed.

     ERR_load_crypto_strings() registers the error strings for all crypto(3)
     functions.  SSL_load_error_strings() does the same, but also registers
     the ssl(3) error strings.

     If the error strings were already loaded before, no action occurs.

     ERR_free_strings() frees all previously loaded error strings.

SEE ALSO
     ERR(3), ERR_error_string(3), OPENSSL_config(3)

HISTORY
     ERR_load_crypto_strings() and SSL_load_error_strings() first appeared in
     SSLeay 0.4.4.  ERR_free_strings() first appeared in SSLeay 0.5.1.  These
     functions been available since OpenBSD 2.4.

BUGS
     Even though the error strings are already compiled into the object code
     of the library as static strings, these functions store them again using
     dynamically allocated memory on the heap.  That may fail if insufficient
     memory is available, but these functions do not report such errors.
     Instead, they fail silently, possibly having registered none or only a
     part of the strings requested.
