Gets the code corresponding to the error message from the last function called.

Synopsis

#include <imsl.h>

long imsl_error_code ( )

Return Value

This function returns the error message code from the last IMSL function called. The include file imsl.h defines a name for each error code.

Example

This example turns off stopping on IMSL_TERMINAL error messages and generates an error by calling imsl_error_options. See Chapter 2, “Eigensystem Analysis” with an illegal value for IMSL_SET_PRINT. The error message code number is retrieved and printed. In imsl.h, IMSL_INTEGER_OUT_OF_RANGE is defined to be 132.

#include <imsl.h>
#include <stdio.h>

main()
{
    long       code;
                                /* Turn off stopping IMSL_TERMINAL */
                                /* messages and print error messages */
                                /* on standard output. */
    imsl_error_options(IMSL_SET_STOP, IMSL_TERMINAL, 0,
                       IMSL_SET_ERROR_FILE, stdout,
                       0);
                                /* Call imsl_error_options() with */
                                /* an illegal value */
    imsl_error_options(IMSL_SET_PRINT, 100, 0,
                       0);
                                /* Get the error message code */
    code = imsl_error_code();
    printf("error code = %d\n", code);
}

Output

*** TERMINAL Error from imsl_error_options."type" must be between 1 and 5,
***          but "type" = 100.

error code = 132
