Syntax

[C/C++:]
void gEnqSavdraSegList(GFILE *fp, int list[], int n, int *count);

[F90:]
subroutine gEnqSavdraSegList(unit, list, n, count)

integer, intent(in) :: unit,n
integer, intent(out) :: list(*),count

Arguments

fp
GINO-C file pointer

unit
Fortran 90 File unit

list
Integer array returning segment identifiers

n
Number of segment identifiers to return

= 0,	Nothing returned in list

count
Number of segment identifiers contained in the metafile

Description

The routine gEnqSavdraSegList() returns a list of segments contained in the opened SAVDRA metafile. The complete metafile is scanned but no graphical information is interpreted.

The metafile should be opened prior to calling this routine using the function gFopen(), with the file pointer or unit number passed as appropriate.

The array list should be declared of length n, and no more than that number of identifiers are returned. The argument count returns the actual number of segment identifiers contained in the file even if this number is greater then n. If count = 0 then the metafile only contains information in segment zero.

If n is less than or equal to zero, no numbers are returned in list. If n is less than zero, a warning message is output.
