OSSL_LIB_CTX...F_DIAGNOSTICS(3ossl)

💖 OSSL_LIB_CTX...F_DIAGNOSTICS 💖

okay bestie, welcome to the 3ossl manual page for the config-diagnostics duo: OSSL_LIB_CTX_set_conf_diagnostics and OSSL_LIB_CTX_get_conf_diagnostics. this is where OpenSSL keeps the lil switch that decides whether it tells you about config problems or just silently vibes past them. no cap. 🌸

---

✨ NAME ✨

OSSL_LIB_CTX_set_conf_diagnostics, OSSL_LIB_CTX_get_conf_diagnostics — set and get configuration diagnostics. like, the on/off for "hey girl, ur config is broken" energy. 🎀

---

🦋 SYNOPSIS 🦋

#include <openssl/crypto.h>

void OSSL_LIB_CTX_set_conf_diagnostics(OSSL_LIB_CTX *ctx, int value);
int OSSL_LIB_CTX_get_conf_diagnostics(OSSL_LIB_CTX *ctx);

---

💅 DESCRIPTION 💅

set it: OSSL_LIB_CTX_set_conf_diagnostics()

so this one sets the value of the configuration diagnostics flag. and listen — if value is nonzero, then subsequent parsing and application of configuration data can report errors that would otherwise be ignored. that's the whole glow-up: errors that used to be silently swept under the rug now get to speak. 🗣️✨

in particular, any errors in the ssl configuration module will cause a failure of SSL_CTX_new(3) and SSL_CTX_new_ex(3) calls. yeah. it's giving consequences. 💀

plot twist tho: the configuration diagnostics flag can also be set when a configuration file is being loaded into OSSL_LIB_CTX with OSSL_LIB_CTX_load_config(3). and if the configuration sets a config_diagnostics value as described in config(5), it will override the value set by OSSL_LIB_CTX_set_conf_diagnostics() before loading the configuration file. so like, the config file gets the final say, bestie. periodt. 👑

get it: OSSL_LIB_CTX_get_conf_diagnostics()

this one just returns the current value of the configuration diagnostics flag. that's it, that's the whole job. main character of no drama. 🫶

---

🌈 RETURN VALUES 🌈

OSSL_LIB_CTX_get_conf_diagnostics() returns 0 if the configuration diagnostics should not be performed, and nonzero otherwise. simple as. 💖
