You misunderstand. A process can call setrlimit() and reduce the number of open file desriptors allowed by the process. Or it can be reduced for all users.

The kernel on some versions of unix can be reconfigured to allow more than 1024 open file descriptors.

The point: You cannot depend on 1024

NAME
vdltodmx - dmx configuration file parser and printer SYNOPSIS
vdltodmx infile outfile DESCRIPTION
vdltodmx reads the input file, which should be in VDL configuration file format. After a successful parse, a file in Xdmx configuration file format is written to the output file. The VDL file format is used with xmovie, which is available from http://www.llnl.gov/icc/lc/img/xmovie/xmovie.html EXAMPLE
Given the following VDL-format file: 0 2 # # 2560 2048 Left two-thirds [restrict=*:2] 2 :2.1 1280 2048 0 0 0 0 :2.2 1280 2048 1280 0 0 0 4 1280 1024 0 0 1280 1024 0 1024 1280 1024 1280 0 1280 1024 1280 1024 # 2560 2048 Right two-thirds [restrict=*:2] 2 :2.2 1280 2048 0 0 0 0 :2.3 1280 2048 1280 0 0 0 4 1280 1024 1280 0 1280 1024 1280 1024 1280 1024 2560 0 1280 1024 2560 1024 the following DMX-format file will be produced: # # virtual "Left two-thirds" 2560x2048 { display :2.1 1280x2048; display :2.2 1280x2048 @1280x0; } # virtual "Right two-thirds" 2560x2048 { display :2.2 1280x2048; display :2.3 1280x2048 @1280x0; } BUGS
If the VDL file is not in the expected format, the program will probably dump core. SEE ALSO
