🌸 SSL_SET_MAX_SEND_FRAGMENT(3) 🌸

Okay bestie, welcome to the Library Functions Manual page for SSL_SET_MAX_SEND_FRAGMENT(3). Tiny header note: it spells the title SSL_SET_MAX_SEND_FRAGMEN(3) up top — the T ghosted us, no cap — but the footer and page name use the full SSL_SET_MAX_SEND_FRAGMENT(3). We proceed, gorgeous. 💅

🎀 NAME 🎀

SSL_CTX_set_max_send_fragment, SSL_set_max_send_fragment — control fragment sizes. That's the whole assignment, bestie: fragment sizes are getting controlled. 💖

✨ SYNOPSIS ✨

library “libssl” libcrypto #include <openssl/ssl.h>

long
SSL_CTX_set_max_send_fragment(SSL_CTX *ctx, long m);

long
SSL_set_max_send_fragment(SSL *ssl, long m);

💅 DESCRIPTION 💅

So SSL_CTX_set_max_send_fragment() and SSL_set_max_send_fragment() set the max_send_fragment parameter for SSL_CTX and SSL objects respectively. Respectively! We love a precise queen. 👑

This value restricts the amount of plaintext bytes that will be sent in any one SSL/TLS record. By default its value is SSL3_RT_MAX_PLAIN_LENGTH (16384). These functions will only accept a value in the range 512 - SSL3_RT_MAX_PLAIN_LENGTH. Lowkey strict, highkey fair. ✨

These functions are implemented using macros. Macro girlies, stand up. 🧚

🦋 RETURN VALUES 🦋

These functions return 1 on success or 0 on failure. Binary icon behavior, periodt. 💀

🌈 SEE ALSO 🌈

🎀 HISTORY 🎀

SSL_CTX_set_max_send_fragment() and SSL_set_max_send_fragment() first appeared in OpenSSL 1.0.0 and have been available since OpenBSD 4.9. History besties, rise. 💜

And that's the whole page, bestie. The footer says this cutie is from Debian, dated June 8, 2025, and answers to SSL_SET_MAX_SEND_FRAGMENT(3). 🫶💖
