2014-01-06const-qualify the address argument to dladdrRich Felker1-1/+1
this agrees with implementation practice on glibc and BSD systems, and is the const-correct way to do things; it eliminates warnings from passing pointers to const. the prototype without const came from seemingly erroneous man pages.
2013-06-29implement minimal dlinfo functionRich Felker1-0/+3
2013-01-23add RTLD_NODELETE flag for dlopenRich Felker1-0/+1
this is a trivial no-op, because dlclose never deletes libraries. thus we might as well have it in the header in case some application wants it, since we're already providing it anyway.
2013-01-23add support for RTLD_NOLOAD to dlopenRich Felker1-0/+1
based on patch by Pierre Carrier <pierre@gcarrier.fr> that just added the flag constant, but with minimal additional code so that it actually works as documented. this is a nonstandard option but some major software (reportedly, Firefox) uses it and it was easy to add anyway.
2012-09-07default features: make musl usable without feature test macrosRich Felker1-5/+1
the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-09-06dladdr should be available under _BSD_SOURCE as well as _GNU_SOURCERich Felker1-1/+1
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker1-1/+7
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-08-26dladdr support for dynamic linker (nonstandard extension)Rich Felker1-0/+10
based on patches submitted by boris brezillon. this commit also fixes the issue whereby the main application and libc don't have the address ranges of their mappings stored, which was theoretically a problem for RTLD_NEXT support in dlsym; it didn't actually matter because libc never calls dlsym, and it seemed to be doing the right thing (by chance) for symbols in the main program as well.
