Hi,
I want to know how big the heap size is from some places of my
program. In AIX I used mallinfo(). But in Linux, I tried 'man
mallinfo' but returned no result. I tried to compile my program in
Linux, it passed, but mallinfo() just return a structure mallinfo of
all zero. I googled and found mallinfo did exist at least in previous
old Linux. So is currently mallinfo() obsolete from Linux? If so, what
else library calls should I use to get the current heap size?
Thanks. |

I googled and found both mallopt/mallinfo were dropped by POSIX 2008.
So is there an equivalent of mallinfo in current Linux?
Thanks. |

I see the entry points do exist in libc.so.6 but I think they are
morely undocumented.
Thanks

They are not. The 'real' glibc documentation is in info format and
manpages may or may not be accurate and may or may not exist[*]. The
relevant section is 3.2.2.11:
You can get information about dynamic memory allocation by calling the
`mallinfo' function. This function and its associated data type are
declared in `malloc.h'; they are an extension of the standard SVID/XPG
version.
[...]
This text should be accessible by using the 'info libc' command. NB:
This program doesn't support vi-keybindings, at least not by default. |
