+.SH DESCRIPTION
+.I intptr_t
+is a signed integer type
+such that any valid
+.RI ( "void *" )
+value can be converted to this type and then converted back.
+It is capable of storing values in the range
+.RB [ INTPTR_MIN ,
+.BR INTPTR_MAX ].
+.P
+.I uintptr_t
+is an unsigned integer type
+such that any valid
+.RI ( "void *" )
+value can be converted to this type and then converted back.
+It is capable of storing values in the range
+.RB [ 0 ,
+.BR INTPTR_MAX ].
+.P
+The macros
+.RB [ U ] INTPTR_WIDTH
+expand to the width in bits of these types.
+.P
+The macros
+.RB [ U ] INTPTR_MAX
+expand to the maximum value that these types can hold.
+.P
+The macro
+.B INTPTR_MIN
+expands to the minimum value that
+.I intptr_t
+can hold.
+.P
+The length modifiers for the
+.RI [ u ] intptr_t
+types
+for the
+.BR printf (3)
+family of functions
+are expanded by the macros
+.BR PRIdPTR ,
+.BR PRIiPTR ,
+and
+.B PRIuPTR
+(defined in
+.IR <inttypes.h> );
+resulting commonly in
+.B %"PRIdPTR"
+or
+.B %"PRIiPTR"
+for printing
+.I intptr_t
+values.
+The length modifiers for the
+.IR [ u ] intptr_t
+types
+for the
+.BR scanf (3)
+family of functions
+are expanded by the macros
+.BR SCNdPTR ,
+.BR SCNiPTR ,
+and
+.B SCNuPTR
+(defined in
+.IR <inttypes.h> );
+resulting commonly in
+.B %"SCNuPTR"
+for scanning
+.I uintptr_t
+values.
+.SH STANDARDS
+C11, POSIX.1-2008.
+.SH HISTORY
+C99, POSIX.1-2001.
+.SH NOTES
+The following header also provides these types:
+.IR <inttypes.h> .
