Full Discussion: stack region
Top Forums UNIX for Advanced & Expert Users stack region Post 302101228 by jim mcnamara on Friday 29th of December 2006 08:34:57 AM

Code:
struct rlimit rlim;
getrlimit(RLIMIT_STACK, &rlim);
printf("STACK: cur - %ld max - %ld\n", rlim.rlim_cur, rlim.rlim_max);

rlim.rlim_cur shows current usage for the process. I think the OP wants all stack usage (across all processes), which I have no idea how to get. That would be totally internal to the kernel for each OS.

NAME
explain_getrlimit_or_die - get resource limits and report errors SYNOPSIS
#include <libexplain/getrlimit.h> void explain_getrlimit_or_die(int resource, struct rlimit *rlim); DESCRIPTION
The explain_getrlimit_or_die function is used to call the getrlimit(2) system call. On failure an explanation will be printed to stderr, obtained from explain_getrlimit(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example: explain_getrlimit_or_die(resource, rlim); resource The resource, exactly as to be passed to the getrlimit(2) system call. rlim The rlim, exactly as to be passed to the getrlimit(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
getrlimit(2) get resource limits explain_getrlimit(3) explain getrlimit(2) errors exit(2) terminate the calling process COPYRIGHT
