Scierror

Arguments

error_level

an integer value specifying an error level

format

a char* string. Specifies a character string combining literal characters with conversion specifications.

value_i

Specifies the data to be converted according to the format parameter.

returns

If the operation is successful, this function returns the number of characters printed (not including the trailing '\0' used to end output to strings).

If an error occurred, a negative value is returned.

Description

Scierror is a C gateway function which displays an error message to the user (same profile as the printf function) and returns an integer value specifying an error level. You must include Scierror.h to benefit from this function. This header is provided in the output_stream module (this directory should be included by default).

Examples

In this example, the C gateway function prints an error message and returns the error level 133.

#include <stack-c.h>
#include <Scierror.h>

int sci_myscierror(char * fname)
{
  Scierror(133,"An error has occurred: %d\n", 1);

  return 0;
}
