Summary

0001569: pointer is not a C-Language Data Type

Description

The <unistd.h> and c99 pages have several uses of pointer as if it were a C-Language Data Type. For example the description of _POSIX_V7_LP64_OFF64 has:

32-bit int and 64-bit long, pointer, and off_t types

In addition to being a misuse of the typographic convention for data types, this also seems to assume/require that all pointers are the same width in each of the ILP32_OFF32, ILP32_OFFBIG, and LP64_OFF64 compilation environments, and that all pointers are at least 64 bits in LPBIG_OFFBIG. The desired action assumes that this is intentional. If it is not, then we'll need an alternative change that only states width requirements for the pointer to void type.

Desired Action

On page 438 line 14979 section <unistd.h>, and
page 439 line 14991 section <unistd.h>, and
page 441 line 15115 section <unistd.h>, and
page 442 line 15119 section <unistd.h>, and
page 442 line 15123 section <unistd.h>, change:

32-bit int, long, pointer, and off_t types.

to:

32-bit int, long, off_t, and all pointer types.

On page 438 line 14982 section <unistd.h>, and
page 439 line 14994 section <unistd.h>, and
page 442 line 15127 section <unistd.h>, and
page 442 line 15132 section <unistd.h>, and
page 442 line 15137 section <unistd.h>, change:

32-bit int, long, and pointer types and an off_t type using at least 64 bits.

to:

32-bit int, long, and all pointer types and an off_t type using at least 64 bits.

On page 438 line 14985 section <unistd.h>, and
page 439 line 14997 section <unistd.h>, and
page 442 line 15142 section <unistd.h>, and
page 442 line 15147 section <unistd.h>, and
page 442 line 15152 section <unistd.h>, change:

32-bit int and 64-bit long, pointer, and off_t types.

to:

a 32-bit int type and 64-bit long, off_t, and all pointer types.

On page 439 line 14988 section <unistd.h>, and
page 439 line 15000 section <unistd.h>, and
page 442 line 15157 section <unistd.h>, and
page 442 line 15162 section <unistd.h>, and
page 443 line 15167 section <unistd.h>, change:

an int type using at least 32 bits and long, pointer, and off_t types using at least 64 bits.

to:

an int type using at least 32 bits and long, off_t, and all pointer types using at least 64 bits.

On page 2547 line 82425 section c99, change:

pointer

to:

pointer types

On page 2549 line 82539 section c99, change:

32-bit int, long, and pointer types and an off_t type using at least 64 bits

to:

32-bit int, long, and all pointer types and an off_t type using at least 64 bits
