libssh2_sftp_seek64 - set the read/write position within a file
#include <libssh2.h> #include <libssh2_sftp.h> void libssh2_sftp_seek64(LIBSSH2_SFTP_HANDLE *handle, libssh2_uint64_t offset);
handle - SFTP File Handle as returned by libssh2_sftp_open_ex
offset - Number of bytes from the beginning of file to seek to.
Move the file handle's internal pointer to an arbitrary location. libssh2 implements file pointers as a localized concept to make file access appear more POSIX like. No packets are exchanged with the server during a seek operation. The localized file pointer is simply used as a convenience offset during read/write operations.
You MUST NOT seek during writing or reading a file with SFTP, as the internals use outstanding packets and changing the "file position" during transit will results in badness.
