Standard Input & Output (STDIO) limits the number of file descriptors to 256 in a 32-bit application.

(Doc ID 1018889.1)

Last updated on MAY 31, 2015

Applies to:

Solaris SPARC Operating System - Version 8.0 and later
All Platforms


 Even when the file descriptor limit is set beyond 256 (i.e. via limit or ulimit on the shell), the maximum number of file pointers that can be opened
by STDIO functions (for instance fopen(), fdopen(), and popen()) is still limited to 256 in a 32-bit application.

File descriptor numbers range from 0 to 255.
