CL Name Style:


1 Purpose

x04ncc takes, as a string argument, the name of a NAG error (e.g., NE_BAD_PARAM) and returns, as an int, the corresponding fail code for the given NAG error.

2 Specification

#include <nag.h>
int  x04ncc (const char *error_name)
The function may be called by the names: x04ncc or nag_error_name_to_code.

3 Description

x04ncc takes, as a string argument, the name of a NAG error (e.g., NE_BAD_PARAM) and returns, as an int, the corresponding fail code for the given NAG error. If the input string does not correspond to a NAG error name then the function returns -1.
Converting the error name to int may be useful when the NAG Header Files are not available, but the int value of an error name is required, say, for checking fail.code following a call to a NAG function.

4 References

None.

5 Arguments

1: error_name const char * Input
On entry: the value of a NAG enumeration member.

6 Error Indicators and Warnings

If the value -1 is returned then the input value is not recognized as a valid NAG fail code.

7 Accuracy

Not applicable.

8 Parallelism and Performance

x04ncc is not threaded in any implementation.

9 Further Comments
