Here is a small program and perfs file that demonstrates the problem.
main.cpp
#include <unistd.h>
#include <string.h>
#include <malloc.h>
#include <FL/Fl.H>
#include <FL/Fl_Preferences.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.H>
char **str_tbl;
int main (void)
{
int entries, loop, str_len;
char path[512], name[8];
Fl_Preferences *preference;
getcwd(path, 512);
preference = new Fl_Preferences(path, "I will never tell", "en");
entries = preference->entries(); // this should return 15 with the
preference file supplied but returns 17
if(!entries)
exit(0);
if((str_tbl = (char **)malloc(sizeof(char *) * entries)) == NULL)
exit(1); // malloc failed
for(loop = 0; loop < entries; ++loop)
{
sprintf(name, "%d", loop);
if(!preference->entryExists(name))
exit(2); // should not get to this but loop will have a value of
15 at this point
if((str_len = preference->size(name)) == 0)
exit(3); // oops, name exists but there is no value
if((str_tbl[loop] = (char *)malloc(sizeof(char) * str_len + 1)) ==
NULL)
exit(1); // malloc failed
preference->get((const char *)name, str_tbl[loop], "", str_len +
1);
}
exit(0); // all is well
}
// a snippet from the fluid generated source file
