I am asking about Linux and not AIX. -cH does not work AIX only on Linux. the manual says ulimit -Hc. The -Hc works on both. Since I have a Linux OS, do i really need to change -cH to -Hc ? Because it will require a an app reboot. Any thoughts if if I leave it as -cH on my Linux box if it will cause an issue !
Thanks

ulimit
ulimit(3) Library Functions Manual ulimit(3)NAME
ulimit - Sets and gets process limits
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <ulimit.h>
long int ulimit (
int command,
... );
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
ulimit(): XSH4.2
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the form of control. The command parameter can have the following values: Returns the soft file size limit of the process. The
limit is reported in 512-byte blocks (see the sys/param.h file) and is inherited by child processes. The function can read files of any
size.
The return value is the integer part of the soft file size limit divided by 512. If the result cannot be represented as a long int,
the result is unspecified. Sets the hard and soft process file size limit for output operations to the value of the second parame-
ter, taken as a long int value, and returns the new file size limit. Any process can decrease its own hard limit, but only a
process with superuser privileges can increase the limit.
The hard and soft file size limits are set to the specified value multiplied by 512. If the result would overflow an rlim_t, the
actual value set is unspecified. [Tru64 UNIX] Returns the maximum possible break value as described in the brk(2) reference page.
DESCRIPTION
The ulimit() function controls process limits.
During access to remote files, the process limits of the local node are used.
NOTES
The ulimit() function is implemented with calls to setrlimit(). The two interfaces should not be used in the same program. The result of
doing so is undefined.
RETURN VALUES
Upon successful completion, ulimit() returns the value of the requested limit and does not change the setting of errno. Otherwise, a value
of -1 is returned, and errno is set to indicate the error.
ERRORS
If the ulimit() function fails, the limit remains unchanged and errno is set to one of the following values: The command parameter is
invalid. A process without appropriate system privileges attempted to increase its file size limit.
As all return values are permissable in a successful situation, an application wishing to check for error situations should set errno to 0,
then call ulimit(), and, if it returns -1, check to see if errno is nonzero.
