Function Documentation

atoi_octal()

static ulong atoi_octal ( const char *  str )

static

my_abort()

void my_abort

(

)

Calls our own implementation of abort, if specified, or std's abort().

set_my_abort()

void set_my_abort

(

void(*)()

new_my_abort_func

)

Sets a new function to be called on my_abort().

Parameters

new_my_abort_func

pointer to a new my_abort function. It can't be [[noreturn]] as pointers to methods can't have attributes.
