error_message
Gets the text of the error message from the last function called.
Synopsis
#include <imsls.h>
char *imsls_error_message ()
Return Value
Returns the current error message.
Description
If the current error type is positive then the last error message set is returned. It does not matter if the error message was printed or not. The current error type is the number returned by
imsls_error_type. If the current error type is zero then
NULL is returned.
The returned string can be freed using
imsls_free.
Example
This example retrieves the error message from a call to
imsls_f_wilcoxon_rank_sum with an illegal argument.
#include <imsls.h>
#include <stdio.h>
int main(void)
{
char *msg;
float x[] = {0, 1, 2};
float y[] = {0, 1, 2};
float p;
p = imsls_f_wilcoxon_rank_sum (3, x, 3, y, 0);
msg = imsls_error_message();
printf("type = %d\ncode = %d\nmsg = %s\n",
imsls_error_type(), imsls_error_code(), msg);
imsls_free(msg);
}
Output
*** WARNING Error IMSLS_AT_LEAST_ONE_TIE from imsls_f_wilcoxon_rank_sum.
*** At least one tie is detected between the samples.
