* ltdl.m4: Bump serial number.
General reformat and tify up in line with Autoconf-2.50 support. (AC_LTDL_FUNC_ARGZ): Test for system implementations of a handful of argz API calls, the error_t type, and the argz.h header. * libltdl/configure.ac (AM_INIT_AUTOMAKE): Bump version number. * libltdl/ltdl.c (rpl_argz_append, rpl_argz_create_sep. rpl_argz_insert, rpl_rgz_next): Fallback implementations of the similarly named functions for machines that don;t use glibc. (lt_dlrealloc): New memory function pointer that can be set by the client. Defaults to rpl_realloc, which in turn uses only lt_dlmalloc and lt_dlfree. (LT_EMALLOC, LT_EREALLOC): Set internal out-of-memory error inside the functions called by these new macros. Simplified all callers by removing explicit client error reporting. (memmove): Fallback implementation of overlap safe memory copy function. (tryall_dlopen): Factorized common code into... (tryall_dlopen_module): ...this new helper function. (canonicalize_path): Changed function signature to return success or failure. Updated all callers. (foreachfile_callback): Make use of argz API. (LT_DLSTRLEN): Moved from here... * libltdl/ltdl.h (LT_STRLEN): ...to here. Updated all callers. (lt_dlrealloc): Declare new memory management handle.

|
||||
handful of argz API calls, the error_t type, and the argz.h

* libltdl/configure.ac (AM_INIT_AUTOMAKE): Bump version number.
|

* libltdl/ltdl.c (rpl_argz_append, rpl_argz_create_sep.
|
||||
rpl_argz_insert, rpl_rgz_next): Fallback implementations of
|
||||
the similarly named functions for machines that don;t use glibc.
|
||||
(lt_dlrealloc): New memory function pointer that can be set by
|

the client. Defaults to rpl_realloc, which in turn uses only
|

(LT_EMALLOC, LT_EREALLOC): Set internal out-of-memory error
|
||||
inside the functions called by these new macros. Simplified all

callers by removing explicit client error reporting.

(memmove): Fallback implementation of overlap safe memory copy
|
||||
function.
|

(tryall_dlopen): Factorized common code into...
|
||||
(tryall_dlopen_module): ...this new helper function.
|
||||
(canonicalize_path): Changed function signature to return success
|
||||
or failure. Updated all callers.
|

(foreachfile_callback): Make use of argz API.
