Detailed Description
Extensions of the strto and wcsto families of functions.
This generally adds default behavior and type safety to these standard C99 functions. The standard defines them only for the types long (strtol), long long (strtoll), intmax_t (strtoimax) and their unsigned variants. This here adds support for the other standard integer types and typedef. This provides
- precise overflow and underflow handling according to the type
- flexible base, namely octal, decimal or hexadecimal conversion
In addition, to provide default arguments for the standard functions, these have names starting with p99_str... and macros that expand to these starting with str..., instead. The later might be reserved or provided in later version of the C standard. If we receive knowledge of such new interfaces we will bracket the definitions given here with appropriate defines.
We provide interfaces for the standard types char (strtoc), signed (strtohh) and unsigned char (strtouhh), signed (strtoh) and unsigned short (strtouh), and signed (strto) and unsigned int (strtou). For the standard typedefs we provide strtouz for size_t and strtot for ptrdiff_t. Here the endings of the names are taken in analogy from the printf formats.
The type specific upper an lower bounds for all these are the MIN and MAX values of the corresponding types.
For the types {u}int_least[N]_t with N = 8, 16, 32 or 64 we provide functions and macros strto{u|i}[N] that have the bounds INT[N]_MIN, INT[N]_MAX and UINT[N]_MAX, respectively. So e.g for strtou16 the bound is not the bound of the type uint_least16_t (which might be much wider than 16 bit) but the value UINT16_MAX, i.e 216-1.
