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 freeed 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);
}
