Salut,
Nu am inteles f. bine, daca vrei sa faci din acelasi program sau din altul,
dar merge folosing gdb, si atasind-ul la programul la care vrei sa vezi
stiva.
Poti folosi codul de mai jos, vezi sa pui informatiile de debug in
executabil (-g) :
void debug_stack(int up_frames, int show_stack, int show_calling_function,
int show_source_info, int show_functions,
char * show_types, char * show_expressions)
{
char s[2000];
char * GDB_CONFIG_FILE;
char executable[10000];
for (int i=0; i<10000; i++)
executable[i]=0;
#ifdef __linux__
readlink("/proc/self/exe", executable, 10000);
#elif __CYGWIN__
sprintf(executable,"my_app.exe");
#else
#error Implement this ....
#endif
GDB_CONFIG_FILE="/tmp/DEBUG_CRASH_FILE";
FILE * fout;
fout = fopen(GDB_CONFIG_FILE,"wt");
fprintf(fout,"set verbose off\nset confirm off\nset pagination off\n");
if (show_stack)
fprintf(fout,"bt\n");
if (show_calling_function)
{
sprintf(s,"frame %d\nlist -\nlist +\n",3+up_frames);
fprintf(fout,s);
}
if (show_functions)
fprintf(fout,"info functions\n");
if (show_source_info)
fprintf(fout,"info source\n");
if (show_types)
{
char * token;
char * kk;
kk = strdup(show_types);
token = strtok(kk," ");
while (token)
{
fprintf(fout,"echo Type of [%s] : \n",token);
fprintf(fout,"ptype %s\n",token);
token = strtok(NULL," ");
};
free(kk);
}
if (show_expressions)
{
char * token;
char * kk;
kk = strdup(show_expressions);
token = strtok(kk," ");
fprintf(fout,"frame 4\n");
while (token)
{
fprintf(fout,"echo Value of [%s] : \n",token);
fprintf(fout,"print %s\n",token);
token = strtok(NULL," ");
};
free(kk);
}
fprintf(fout,"detach\n");
fclose(fout);
sprintf(s, "gdb %s %d --batch --quiet -x %s 2>/dev/null", executable,
getpid(), GDB_CONFIG_FILE);
system(s);
return;
}
