explain_setenv_or_die(3) Library Functions Manual explain_setenv_or_die(3)NAME
explain_setenv_or_die - change or add an environment variable and report errors
SYNOPSIS
#include <libexplain/setenv.h>
void explain_setenv_or_die(const char *name, const char *value, int overwrite);
int explain_setenv_on_error(const char *name, const char *value, int overwrite);
DESCRIPTION
The explain_setenv_or_die function is used to call the setenv(3) system call. On failure an explanation will be printed to stderr, obtained
from the explain_setenv(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_setenv_on_error function is used to call the setenv(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_setenv(3) function, but still returns to the caller.
name The name, exactly as to be passed to the setenv(3) system call.
value The value, exactly as to be passed to the setenv(3) system call.
overwrite
The overwrite, exactly as to be passed to the setenv(3) system call.
RETURN VALUE
The explain_setenv_or_die function only returns on success, see setenv(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_setenv_on_error function always returns the value return by the wrapped setenv(3) system call.
EXAMPLE
The explain_setenv_or_die function is intended to be used in a fashion similar to the following example:
explain_setenv_or_die(name, value, overwrite);
