gsasl_free(3)

πŸ’– gsasl_free β€” bestie, we're freeing the memory πŸ’–

okay so this is gsasl_free(3), a page from the gsasl manual. yes it's short. no it's not boring. it is, in fact, iconic, and here's why πŸ‘‘


✨ NAME ✨

gsasl_free β€” it's an API function, periodt πŸ’…


✨ SYNOPSIS ✨

#include <gsasl.h>

void gsasl_free(void * ptr);

literally that's the whole vibe. look at her. so simple. so powerful. πŸ¦‹


✨ ARGUMENTS ✨

  • void * ptr β€” a memory pointer πŸŽ€ like, the pointer you wanna hand over. the one that's holding your lil allocated bytes.

✨ DESCRIPTION ✨

so what does she do? she invokes free( ptr ) to de-allocate that memory pointer. that's it. that's the whole job, and she does it flawlessly ✨

typically you're gonna use this on strings that were allocated by other libgsasl functions β€” so like, if libgsasl handed you a string, you hand it back here when you're done. give it back. let it go. main character energy fr fr 🫢

now here's where it gets lowkey important: this is useful on Windows πŸ‘€ where libgsasl is linked to one CRT and the application is linked to another CRT. and when that happens, malloc/free will not use the same heap. 😭 two different heaps, two different worlds, they simply do not know each other.

this specific situation happens if you build libgsasl using mingw32 and the application with Visual Studio. no cap. so like, don't just call raw free() yourself there β€” call gsasl_free and let her handle the cross-CRT diva drama πŸ’…
