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... (6 Replies)

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... (2 Replies)

My program is not dumping core when hitting a segmentation violation inside a thread.

setsid
SETSID(2) BSD System Calls Manual SETSID(2)
NAME
setsid -- create session and set process group ID
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
pid_t
setsid(void);
DESCRIPTION
The setsid function creates a new session. The calling process is the session leader of the new session, is the process group leader of a
new process group and has no controlling terminal. The calling process is the only process in either the session or the process group.
Upon successful completion, the setsid function returns the value of the process group ID of the new process group, which is the same as the
process ID of the calling process.
ERRORS
If an error occurs, setsid returns -1 and the global variable errno is set to indicate the error, as follows:
[EPERM] The calling process is already a process group leader, or the process group ID of a process other than the calling process
matches the process ID of the calling process.
SEE ALSO
setpgid(3), tcgetpgrp(3), tcsetpgrp(3)
STANDARDS
The setsid function is expected to be compliant with the IEEE Std 1003.1-1988 (``POSIX.1'') specification.
