NAME
Ns_ConnCopyToChannel, Ns_ConnCopyToDString, Ns_ConnCopyToFd, Ns_ConnCopyToFile - Copy request content to open file or dstring
SYNOPSIS
#include "ns.h" int Ns_ConnCopyToChannel(conn, ncopy, chan) int Ns_ConnCopyToDString(conn, ncopy, dsPtr) int Ns_ConnCopyToFd(conn, ncopy, fd) int Ns_ConnCopyToFile(conn, ncopy, fp)
ARGUMENTS
Ns_Channel chan (in) Pointer to Tcl channel open for write. Ns_Conn conn (in) Pointer to open connection. Ns_DString dsPtr (in) Initialized dstring. int fd (in) File descriptor open for write. FILE fp (in) Stdio FILE pointer open for write. int ncopy (in) Number of bytes to copy. _________________________________________________________________
DESCRIPTION
These functions copy content from an open connection request to the given open file descriptor, FILE, dstring, or Tcl_Channel. The rou- tines work by copying from the content buffer; see the man page on Ns_ConnContent for how this buffer is managed for both small and large requests. The functions all return the number of bytes copied which will match the requested ncopy argument unless there is an error writing the con- tent or the requested bytes is greater than the number of bytes still available to be read. An internal offset into the connection is maintained and is shared with routines such as Ns_ConnRead which also consume content from the same buffer. Note that routines which access the entire content, e.g., Ns_ConnContent, Ns_ConnContentFd, or Ns_ConnGetQuery will continue to provide access to the entire request regardless if one of the Ns_ConnCopy or Ns_ConnRead functions have been used.
EXAMPLES
The following example demonstrates copying user data to a temp file: fd = open("myfile.out", O_WRONLY|O_BINARY); len = Ns_ConnContentLength(conn); if (Ns_ConnCopyToFd(conn, len, fd) != len) { ... error writing content or content already consumed ... }
