.SH DESCRIPTION
|
2007-04-13 01:30:03 +04:00
|
|
|
Reads a block of data from an LIBSSH2_SFTP_HANDLE. This method is modelled
|
2007-02-23 13:20:56 +03:00
|
|
|
after the POSIX \Iread(3)\fP function and uses the same calling
|
|
|
|
semantics. \fIlibssh2_sftp_read(3)\fP will attempt to read as much as possible
|
|
|
|
however it may not fill all of buffer if the file pointer reaches the end or
|
|
|
|
if further reads would cause the socket to block.
|
|
|
|
|
|
|
|
\fIhandle\fP is the SFTP File Handle as returned by \fIlibssh2_sftp_open(3)\fP.
|
|
|
|
|
|
|
|
\fIbuffer\fP is a pointer to a pre-allocated buffer of at least
|
|
|
|
\fIbuffer_maxlen\fP bytes to read data into.
|
|
|
|
.SH RETURN VALUE
|
2007-06-07 20:01:12 +04:00
|
|
|
Number of bytes actually populated into buffer, or -1 on failure. It returns
|
2007-06-08 17:33:08 +04:00
|
|
|
LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
|
|
|
|
LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
