FppRead function

Declaration

function FpPRead(fd: cint; buf: PAnsiChar; nbytes: TSize; offset: TOff)
: TsSize

Description

FpPRead reads nbytes bytes from file descriptor fd into buffer buf starting at offset offset. Offset is measured from the start of the file. This function can only be used on files, not on pipes or sockets (i.e. any seekable file descriptor).

The function returns the number of bytes actually read, or -1 on error.

Errors

On error, -1 is returned.
