The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.

/* To use this file with libraries the following macro is useful:
|
|
|
|
#define _ESTREAM_EXT_SYM_PREFIX _foo_
|
|
|
|
This prefixes all external symbols with "_foo_".
|
|
|
|
For the implementation of the code (estream-printf.c) the following
|
|
macros may be used to tune the implementation for certain systems:
|
|
|
|
#define _ESTREAM_PRINTF_REALLOC foo_realloc
|
|
|
|
Make estream_asprintf and estream_vasprintf use foo_realloc
|
|
instead of the standard realloc to allocate memory returned to
|
|
the caller. Note that foo_realloc needs to be C-90 compliant:
|
|
foo_realloc (NULL,n) is the same as a call to malloc(n) and
|
|
foo_realloc (a, 0) is the same as a call to free (a).
|
|
|
|
#define _ESTREAM_PRINTF_EXTRA_INCLUDE "foo.h"
|
|
|
|
This includes the file "foo.h" which may provide prototypes for
|
|
the custom memory allocation functions.
