4 Routine:
5 int STdecNdouble (const char String[], int Nmin, int Nmax, double Dval[],
6 int *N)
7
8 Purpose:
9 Decode double values (variable number)
10
11 Description:
12 This routine decodes a string containing numeric data. Multiple data items
13 data items in the string are separated by commas or white-space (as defined
14 by the isspace routine). The decoded data is stored as double values. If
15 the number of data values in the string is less than a given minimum number
16 or a decoding error is detected, an error message is printed and an error
17 indication is returned. A warning messages is printed if extra data follows
18 the requested values (this data is ignored).

20 Parameters:
21 <- int STdecNdouble
22 Error status,
23 0 - no error
24 1 - error, too few values or data format error
25 2 - warning, data values too large or too small
26 -> const char String[]
27 Input string
28 -> int Nmin
29 Minimum number of values to be read (may be zero)
30 -> int Nmax
31 Maximum number of values to be read
32 <- double Dval[]
33 Array of Nmax elements used to store the decoded values. Only the first
34 N values are modified.
35 <- int *N
36 Actual number of values decoded. In the case of an error, N indicates
37 the number of values successfully decoded. In that case, N may be less
38 than Nmin.
