We better do this once and for all instead of cluttering all future commits with diffs of trailing white spaces. In the majority of cases blank or single lines are affected and thus this change won't disturb a git blame too much. For future commits the pre-commit scripts checks that this won't happen again.

/* 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_MALLOC foo_malloc
|
|
#define _ESTREAM_PRINTF_FREE foo_free
|
|
|
|
Make estream_asprintf and estream_vasprintf use foo_malloc and
|
|
foo_free instead of the standard malloc and free functions to
|
|
allocate the memory returned to the caller.
|
|
|
|
#define _ESTREAM_PRINTF_EXTRA_INCLUDE "foo.h"
|
|
|
|
This includes the file "foo.h" which may provide prototypes for
|
|
the custom memory allocation functions.
