HP UX Software Transition Kit (STK) manual Showall Use showsymbols to Show All Symbols

}
if ((flags & EXPORT_SYMBOLS)	/* export symbols requested	*/
&& (flags & NO_VALUES)==0)	/* NO_VALUES was NOT specified */
printf(" 0x%8X", symbols->value); /* so display symbol's address */
printf("\n");	/* terminate output line	*/
symbols++;	/* move to next symbol record	*/

return num_symbols;	/* return the number of symbols */

}

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("	TOTAL SYMBOLS: %d\n", num_syms);

}

}

The show_all program shown above was compiled with the command:

$ cc -Aa -o show_all show_all.c show_symbols.c -ldld

NOTE: The following output for the example differs in Itanium/PA64 mode. For example, STORAGE is not supported.

The output produced by running this program is shown below:
