.SH NAME
|
||
|
|
libssh2_sftp_read - read data from an SFTP handle
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <libssh2.h>
|
||
|
|
|
||
|
|
ssize_t libssh2_sftp_read(LIBSSH2_SFTP_HANDLE *handle,
|
||
|
|
char *buffer, size_t buffer_maxlen);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Reads a block of data from an LIBSSH2_SFTP_HANDLE. This method is modeled
|
||
|
|
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
|
||
|
|
Number of bytes actually populated into buffer, or -1 on failure.
