strcmp core dumps

hi everyone, Right now when I do: strcmp(s1, s2); i get a core dump because at times s1 or s2 can be nothing so that makes strcmp() core dump. What is the solution, if at times I expect one of them (or both) to be NULL? I want to be able to compare that s1 is NULL and s2 is "blah" or...

Using GDB to analyse different CORE dumps

Hi, Can we modify the GDB source code so as to analyze core dumps from different targets? From my analysis, I think we need to build our section table statically for each target. i.e., including the various address boundaries in build_section_table() function. If this is the case, then the GDB...

core dumps

i had a situation where a process was defunct. preap would not reap the process and gcore would not work properly (not sure why). therefore, the suggestion was to force a panic and collect the core dump. obviously you could do a savecore -L and capture the dump without bringing down the system....

LEARN ABOUT NETBSD

fincore

FINCORE(1)						    BSD General Commands Manual 						FINCORE(1)

NAME

     fincore -- query in-core status of file pages

SYNOPSIS

     fincore [-qs] file ...

DESCRIPTION

     The fincore utility queries and displays in-core status of specified files.

     Note that the result can already be stale when being output due to other activities in the system.  Thus it should be used only for advisory
     purposes.

     The fincore utility accepts the following options.

     -q        The quiet mode.	Outputs nothing unless the file has in-core pages.

     -s        The summary mode.  Only shows number of pages.

EXAMPLES

     The following example shows that /bin/cat and /bin/cp are fully cached in-core while the other executables are not in-core.  numbers shown in
     the default output are page indexes in the file of each in-core pages.

     % fincore /bin/c*
     /bin/cat: 0 1 2 3
     /bin/chio:
     /bin/chmod:
     /bin/cp: 0 1 2 3 4 5
     /bin/cpio:
     /bin/csh:
     % fincore -s /bin/c*
     /bin/cat: 4 / 4 in-core pages (100.00%)
     /bin/chio: 0 / 5 in-core pages (0.00%)
     /bin/chmod: 0 / 3 in-core pages (0.00%)
     /bin/cp: 6 / 6 in-core pages (100.00%)
     /bin/cpio: 0 / 36 in-core pages (0.00%)
     /bin/csh: 0 / 41 in-core pages (0.00%)

     mincore(2)

AUTHORS

     The fincore utility is written by YAMAMOTO Takashi.

CAVEATS

     The concept of page cache is an implementation detail of the kernel.  The fincore utility works using some assumptions on the current imple-
     mentation.  Thus it might stop working in a future version of NetBSD.

BUGS

     The amount of CPU time the current implementation of fincore utility would take is roughly proportional to the file sizes.  Ideally it should
     be proportional to the number of in-core pages.
