explain_strtod_or_die(3) Library Functions Manual explain_strtod_or_die(3) NAME explain_strtod_or_die - convert string to number and report errors SYNOPSIS #include <libexplain/strtod.h> double explain_strtod_or_die(const char *nptr, char **endptr); double explain_strtod_on_error(const char *nptr, char **endptr)) DESCRIPTION The explain_strtod_or_die function is used to call the strtod(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtod(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_strtod_on_error function is used to call the strtod(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtod(3) function, but still returns to the caller. nptr The nptr, exactly as to be passed to the strtod(3) system call. endptr The endptr, exactly as to be passed to the strtod(3) system call. RETURN VALUE The explain_strtod_or_die function only returns on success, see strtod(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_strtod_on_error function always returns the value return by the wrapped strtod(3) system call. EXAMPLE The explain_strtod_or_die function is intended to be used in a fashion sim- ilar to the following example: double result = explain_strtod_or_die(nptr, endptr); SEE ALSO strtod(3) convert ASCII string to floating-point number explain_strtod(3) explain strtod(3) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_strtod_or_die(3)
