[PATCH v2] system_data_types.7: Improve "Include" wording and format, and explain it in NOTES

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The previous format/wording for the includes wasn't very clear.
Improve it a bit following Branden's proposal.
It also helps reduce lines of code.

Add a subsection in NOTES explaining the conventions used.

Remove the comment for helping maintain the page,
as the NOTES section is now clear enough.

Hi Michael,

After this patch, we're at a sync-point: no more pending patches from me.

Tomorrow I'll go to the mountain, so you can have a small break from me :p

Cheers,

Alex

+.SS Conventions used in this page
+In "Conforming to" we only concern ourselves with
+C99 and later and POSIX.1-2001 and later.
+Some types may be specified in earlier versions of one of these standards,
+but in the interests of simplicity we omit details from earlier standards.
+.PP
+In "Include", we first note the "primary" header(s) that
+define the type according to either the C or POSIX.1 standards.
+Under "Alternatively", we note additional headers that
+the standards specify shall define the type.
 .SH EXAMPLES
 The program shown below scans from a string and prints a value stored in
 a variable of an integer type that doesn't have a length modifier.
