search for: __fd_setsize

Hi, Besides file-max and file-nr is there anywhere else I should be looking to solve a C program giving me 'too many open files' problem? (centos 3.4) While the program is complaining here were the values file-max 209632 file-nr 3655 258 209632 lsof | wc -l around 7000 during and about 1111 less after I closed the application. Any ideas? thx

...elect(maxfd+1, fdset, NULL, NULL, NULL); My question is why don't you use: fdsetsz = sizeof( fd_set ); The 2.4.20 Linux kernel defines fd_set like this: #define __NFDBITS (8 * sizeof(unsigned long)) #define __FD_SETSIZE 1024 #define __FDSET_LONGS (__FD_SETSIZE/__NFDBITS) typedef struct { unsigned long fds_bits [__FDSET_LONGS]; } __kernel_fd_set;...
