recvfrom() causes segmentation fault
hi all....
i wrote a program with udp sockets..
when it reaches the function 'recvfrom()' it crashes with a core dump.
the gdb trace says the following error msg...
Core was generated by `/opt/fmp'.
Program terminated with signal 6, Aborted.
#0 0x00000055555b18e4 in recvfrom () from /lib64/libpthread.so.0
(gdb) c
The program is not being run.
(gdb) bt
#0 0x00000055555b18e4 in recvfrom () from /lib64/libpthread.so.0
#1 0x00000001200054fc in ParseExecuteCommand (sock=6) at ../src/command_mgmt.c:92
#2 0x0000000120004f30 in main (argc=1, argv=0xffffd685f8) at ../src/main.c:586
can anybody tell me when 'recvfrom()' can cause segmenation fault?????

extract_font_range
extract_font_range(3alleg4) Allegro manual extract_font_range(3alleg4)
NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
FONT *extract_font_range(FONT *f, int begin, int end)
DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this
function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the
font. Example:
FONT *myfont;
FONT *capitals;
FONT *fontcopy;
...
/* Create a font of only capital letters */
capitals = extract_font_range(myfont, 'A', 'Z');
/* Create a copy of the font */
fontcopy = extract_font_range(myfont, -1, -1);
...
destroy_font(capitals);
destroy_font(fontcopy);
RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
to avoid memory leaks.
