π libssh2_free(3) π
okay bestie, welcome to the libssh2 manual, page libssh2_free. this is the little cleanup queen of the family and honestly? she's so underrated. β¨
πΈ NAME πΈ
libssh2_free β deallocate libssh2 memory π§Ή
π SYNOPSIS π
#include <libssh2.h>
void
libssh2_free(LIBSSH2_SESSION *session, void *ptr);
π¦ DESCRIPTION π¦
so like. you know how you asked libssh2 for some memory earlier? yeah. this is the function that gives it back. π«Ά
libssh2_free deallocates memory that was allocated by an earlier call to libssh2 functions. it's literally the "put it back where you found it" of the whole library.
and here's the cute part β it doesn't just go rogue and do its own thing. it uses the memory allocation callbacks provided by the application, if any. if the app didn't hand over any callbacks? then it just calls free(). simple. iconic. no drama. π
where is this actually useful tho? mostly under Windows, when libssh2 is linked to one run-time library and the application is linked to another. because mixing run-time libraries and then freeing memory across that boundary is giving chaos π and this function is the one that keeps everything matching up. no cap.
β AVAILABILITY β
added in libssh2 1.2.8 β so she's been holding it down since way back. π
π SEE ALSO π
libssh2_session_init_ex(3)β go say hi to her sister π
and that's the whole page, bestie!! you now know how to free your libssh2 memory correctly, which means you're lowkey doing better than half the internet. main character energy fr fr. ππ¦β¨
this page came from the libssh2 manual, dated 13 Oct 2010, and yes β it's still the same libssh2_free(3) you just read. periodt. π
