Hello,
I have downloaded libssh2 version 0.18 and compiled one of the sample
programs (example\simple\sftp.c) which came with the library on a
Windows system.
Using this sample executable, I wanted to read a 17 megabyte remote file
using the public key authentication.
I also changed the buffer size from 1024 bytes to 256k bytes in line 224
of example\simple\sftp.c.
So following change is made to the buffer size.
From
char mem[1024]; //1k buffer
To
char mem[262144]; // 256k buffer
Upon the completion of the first call to "rc =
libssh2_sftp_read(sftp_handle, mem, sizeof(mem));" in line 228 of the
sftp.c,
the "rc" variable is assigned "-1" indicating that the reading failed.
Using the libssh2_session_last_error call to retrieve the last error, I
get the error code of -30 and the error message of "Timeout waiting for
status message".
It seems like this buffer limit is imposed around 40k bytes.
Anything below this limit, the remote file can be read using this
library successfully.
Does anyone know why this happens?
Thank you.
