To render in Git webviews as-is, to make it easier to edit, verify,
and to sync up with curl.
- add options to not build the `.3` man pages:
- autotools: `--disable-docs`
- cmake: `LIBSSH2_BUILD_DOCS=OFF`
- building `.3` man pages requires Perl after this patch.
- drop `mansyntax` and the shell / `grep` / GNU `man` tool requirements with it.
- scripts and most logic were copied from curl.
- add `cd2nroff` from curl, with edits to relax curl-specific checks.
- used `nroff2cd` (from curl) to convert from `.3` to `.md`. Then
manually fixed copyrights, inline function references and a couple
of other things.

# NAME
|
|
|
|
libssh2_session_last_error - get the most recent error
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <libssh2.h>
|
|
|
|
int
|
|
libssh2_session_last_error(LIBSSH2_SESSION *session,
|
|
char **errmsg, int *errmsg_len, int want_buf);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
*session* - Session instance as returned by libssh2_session_init_ex(3)
|
|
|
|
*errmsg* - If not NULL, is populated by reference with the human
|
|
readable form of the most recent error message.
|
|
|
|
*errmsg_len* - If not NULL, is populated by reference with the length
|
|
of errmsg. (The string is NUL-terminated, so the length is only useful as
|
|
an optimization, to avoid calling strlen.)
|
|
|
|
*want_buf* - If set to a non-zero value, "ownership" of the errmsg
|
|
buffer will be given to the calling scope. If necessary, the errmsg buffer
|
|
will be duplicated.
|
|
|
|
Determine the most recent error condition and its cause.
|
|
|
|
# RETURN VALUE
|
|
|
|
Numeric error code corresponding to the the Error Code constants.
