NAME
FunFlush - flush data to output file
SYNOPSIS
#include <funtools.h>
void FunFlush(Fun fun, char *plist)
DESCRIPTION
The FunFlush routine will flush data to a FITS output file. In particular, it can be called after all rows have been written (using the
FunTableRowPut() routine) in order to add the null padding that is required to complete a FITS block. It also should be called after com-
pletely writing an image using FunImagePut() or after writing the final row of an image using FunTableRowPut().
The plist (i.e., parameter list) argument is a string containing one or more comma-delimited keyword=value parameters. If the plist string
contains the parameter "copy=remainder" and the file was opened with a reference file, which, in turn, was opened for extension copying
(i.e. the input FunOpen() mode also was "c" or "C"), then FunFlush also will copy the remainder of the FITS extensions from the input ref-
erence file to the output file. This normally would be done only at the end of processing.
Note that FunFlush() is called with "copy=remainder" in the mode string by FunClose(). This means that if you close the output file before
the reference input file, it is not necessary to call FunFlush() explicitly, unless you are writing more than one extension. See the
evmerge example code. However, it is safe to call FunFlush() more than once without fear of re-writing either the padding or the copied
extensions.
In addition, if FunFlush() is called on an output file with the plist set to "copy=reference" and if the file was opened with a reference
file, the reference extension is written to the output file. This mechanism provides a simple way to copy input extensions to an output
file without processing the former. For example, in the code fragment below, an input extension is set to be the reference file for a
newly opened output extension. If that reference extension is not a binary table, it is written to the output file:
/* process each input extension in turn */
for(ext=0; ;ext++){
/* get new extension name */
sprintf(tbuf, "%s[%d]", argv[1], ext);
/* open input extension -- if we cannot open it, we are done */
if( !(ifun=FunOpen(tbuf, "r", NULL)) )
break;
/* make the new extension the reference handle for the output file */
FunInfoPut(ofun, FUN_IFUN, &ifun, 0);
/* if its not a binary table, just write it out */
if( !(s=FunParamGets(ifun, "XTENSION", 0, NULL, &got)) ||
strcmp(s, "BINTABLE")){
if( s ) free(s);
FunFlush(ofun, "copy=reference");
FunClose(ifun);
continue;
}
else{
/* process binary table */
....
}
}
