ncl_nerro man page

NERRO — Referenced by a user to obtain the current value of the internal error flag of SETER.

Synopsis

NERR=NERRO(NERRF)

C-Binding Synopsis

#include <ncarg/ncargC.h>

c_nerro(int *nerrf)

Description

The FORTRAN expression "NERRO(NERRF)" has the value of the internal error flag of SETER. If its value is non-zero, this indicates that a prior recoverable error occurred and has not yet been cleared. The argument NERRF is given the same value as the function reference; this is useful in some situations.

The argument of NERRO is as follows:

NERRF
(an output variable of type INTEGER) - Receives the same value that is returned as the value of the function itself.

C-Binding Description

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

Examples

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

Access

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