NAME FunImageGet – get an image or image section SYNOPSIS #include <funtools.h> void *FunImageGet(Fun fun, void *buf, char *plist) DESCRIPTION The FunImageGet() routine returns an binned image array of the specified section of a Funtools data file. If the input data are already of type image, the array is generated by extracting the specified image…
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…

NAME FunColumnLookup – lookup a Funtools column SYNOPSIS #include <funtools.h> int FunColumnLookup(Fun fun, char *s, int which, char **name, int *type, int *mode, int *offset, int *n, int *width) DESCRIPTION The FunColumnLookup() routine returns information about a named (or indexed) column. The first argument is the Fun handle associated with this set of columns. The…
NAME FunColumnActivate – activate Funtools columns SYNOPSIS #include <funtools.h> void FunColumnActivate(Fun fun, char *s, char *plist) DESCRIPTION The FunColumnActivate() routine determines which columns (set up by FunColumnSelect()) ultimately will be read and/or written. By default, all columns that are selected using FunColumnSelect() are activated. The FunColumnActivate() routine can be used to turn off/off activation of…
NAME FunClose – close a Funtools data file SYNOPSIS #include <funtools.h> void FunClose(Fun fun) DESCRIPTION The FunClose() routine closes a previously-opened Funtools data file, freeing control structures. If a Funtools reference handle was passed to the FunOpen() call for this file, and if copy mode also was specified for that file, then FunClose() also will…
