STANDARDS CONFORMANCE
The [EILSEQ] and [EINVAL] errno values are extensions to the ISO/IEC 9899:1999
specification.
The POSIX standards leave some features to the implementing vendor to define. The following
features are affected in the HP implementation:
• The input for a %p conversion by the vwscanf( ) function must be a pointer to a pointer
to void.
• A - (dash) character that is neither the first nor last character in a scanset for %[scanset]
conversion indicates a range of values. The value preceding a - (dash) character must be
lexically less than or equal to the value after the - (dash).
The following are HP extensions to the ISO/IEC 9899:1999 specification:
• The conversion specifier L followed by a d, i, o, u, x,orX conversion specifier indicates
that the argument will be treated as a long long or an unsigned long long, which is a 64-
bit integer data type.
