STANDARDS CONFORMANCE
The [EILSEQ] and [EINVAL] errno values are extensions to the POSIX standards defined in the
XPG4 Version 2 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 fscanf() 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 XPG4 Version 2 specification:
• The conversion specifier L followed by a d, i, n, o,orx conversion code character indi-
cates that the receiving variable is treated as a long long, which is a 64-bit integer data
type.
• The conversion specifier ll followed by a d, i, n, o,orx indicates that the argument will
be treated as an unsigned long long, which is a 64-bit integer data type.
