B_error - Print the error message to stderr
#include <ubf.h>
void B_error (char *str);
Link with -lubf -lnstd -lm -lpthread
The principle is similar to perror() POSIX function call. Function prints the
last UBF error message including user message (in str) to stderr.
Function is void and does not return value.
See ubftest/test_expr.c for sample code.
