PR_OPEN(3PROC) Process Control Library Functions PR_OPEN(3PROC)
pr_open - inject open system call into victim process

int
pr_open(struct ps_prochandle *P, const char *filename, int flags,
mode_t mode);
The pr_open() function injects the open(2) system call into the target
process P by means of the agent LWP. If the process handle P is the
value NULL then this will be equivalent to calling open(2) on the
currently running process.
The arguments filename, flags, and mode have the same meaning as in
open(2). See open(2) for the full description and purpose of the open
system call and its arguments.
The pr_open() function only works on active processes. Process handles
that correspond to core files, zombie processes, or ELF objects do not
support system call injection.
Upon successful completion, the pr_open() function's return value is
that described in open(2). Otherwise, -1 is returned and errno is set
to ENOSYS to indicate that the system call could not be injected.
For the full list of errors see the ERRORS section in open(2).
The pr_open() function will fail if:
ENOSYS An error occurred while trying to invoke the agent
LWP and inject a system call in the process handle P
or the process handle P does not support system call
injection.

ERRORS
