In addition, the extern declaration of the variable __gconv_nmodules refers to a variable that does not exist any more. Considering this, these symbols do not need to be exposed via a header file. This patch removes the extern declarations from the header file and moves the definitions to the compilation units where they are used. ChangeLog: 2017-10-27 Arjun Shankar * iconv/gconv_int.h (__gconv_path_elem): Remove. (__gconv_max_path_elem_len): Likewise. (__gconv_nmodules): Likewise. (__gconv_get_path): Likewise. (path_elem): Move to ... * iconv/gconv_conf.c: ... here. (__gconv_get_path): Mark function static. * iconv/gconv_int.h (GCONV_NCHAR_GOAL): Move to ... * iconv/gconv_open.c: ... here. --- iconv/gconv_conf.c | 9 ++++++++- iconv/gconv_int.h | 21 --------------------- iconv/gconv_open.c | 4 ++++ 3 files changed, 12 insertions(+), 22 deletions(-) diff --git a/iconv/gconv_conf.c b/iconv/gconv_conf.c index d5cf86e..af23e34 100644 --- a/iconv/gconv_conf.c +++ b/iconv/gconv_conf.c @@ -38,6 +38,13 @@ /* This is the default path where we look for module lists. */ static const char default_gconv_path[] = GCONV_PATH; +/* Type to represent search path. */ +struct path_elem +{ + const char *name; + size_t len; +}; + /* The path elements, as determined by the __gconv_get_path function.
