The following example shows the source for a program named show_all.c that calls show_symbols to show all imported and exported symbols for every loaded shared library. It uses shl_get to get the library handles of all loaded libraries.

show_all — Use show_symbols to Show All Symbols

#include <dl.h> #include <stdio.h>

/* prototype for show_syms */

int show_syms(shl_t hndl, short type, int flags); main()

{

int idx, num_syms;

struct shl_descriptor * desc;

for (idx=0; shl_get(idx, &desc) != -1; idx++) /* step through libs */

{

printf(“[%s]\n”, desc->filename); /* show imports & exports for each */

printf(“ Imports:\n”);

num_syms = show_symbols(desc->handle, TYPE_UNDEFINED, IMPORT_SYMBOLS);

printf(“	TOTAL SYMBOLS: %d\n”, num_syms);
printf(“	Exports:\n”);

num_syms = show_symbols(desc->handle, TYPE_UNDEFINED, EXPORT_SYMBOLS);

printf(“

}

}

	The show_all program shown above was compiled with the command:
	$ cc -Aa -o show_all show_all.c show_symbols.c -ldld
