NAME

6       NERRO - Referenced by a user to obtain the current value of the
7       internal error flag of SETER.
8

SYNOPSIS

10       NERR=NERRO(NERRF)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       c_nerro(int *nerrf)
16

DESCRIPTION

18       The FORTRAN expression "NERRO(NERRF)" has the value of the internal
19       error flag of SETER.  If its value is non-zero, this indicates that a
20       prior recoverable error occurred and has not yet been cleared.  The
21       argument NERRF is given the same value as the function reference; this
22       is useful in some situations.
23
24       The argument of NERRO is as follows:
25
26
27       NERRF       (an output variable of type INTEGER) - Receives the same
28                   value that is returned as the value of the function itself.
29

C-BINDING DESCRIPTION

31       The C-binding argument descriptions are the same as the FORTRAN
32       argument descriptions.
33

EXAMPLES

35       Use the ncargex command to see the following relevant examples: tseter,
36       arex02.
37

ACCESS

39       To use nerro or c_nerro, load the NCAR Graphics libraries  ncarg,
40       ncarg_gks, and ncarg_c, preferably in that order.
