X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=eaa2f6e06d2b49e9418f4bb5568f106d2cc2c592;p=strace

Introduce generic STRINGIFY and STRINGIFY_VAL macros

* macros.h (STRINGIFY, STRINGIFY_VAL): New macros.
* mpers_type.h: Include "macros.h".
[IN_MPERS] (STRINGIFY): Remove.
* tests/sockname.c (TEST_SYSCALL_STR__, TEST_SYSCALL_STR_): Remove.
(TEST_SYSCALL_STR): Use STRINGIFY_VAL.
