NAME

explain_sprintf_or_die - formatted output conversion and report errors  

SYNOPSIS

#include <libexplain/sprintf.h>

int explain_sprintf_or_die(char *data, const char *format, ...);
int explain_sprintf_on_error(char *data, const char *format, ...);  

DESCRIPTION

The explain_sprintf_or_die function is used to call the sprintf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_sprintf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_sprintf_on_error function is used to call the sprintf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_sprintf(3) function, but still returns to the caller.

data
The data, exactly as to be passed to the sprintf(3) system call.
format
The format, exactly as to be passed to the sprintf(3) system call.
 

RETURN VALUE

The explain_sprintf_or_die function only returns on success, see sprintf(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_sprintf_on_error function always returns the value return by the wrapped sprintf(3) system call.  

EXAMPLE

The explain_sprintf_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_sprintf_or_die(data, format, ...);
