PR_CREAT(3PROC) Process Control Library Functions PR_CREAT(3PROC)

NAME

pr_creat - inject creat system call into victim process

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
pr_creat(struct ps_prochandle *P, const char *filename, mode_t mode);

DESCRIPTION

The pr_creat() function injects the creat(2) system call into the
target process P by means of the agent LWP. If the process handle P is
NULL then this is equivalent to calling creat(2) on the currently
running process.

The arguments filename and mode have the same meaning as in creat(2).
See creat(2) for the full description and purpose of the creat system
call and its arguments.

The pr_creat() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects
do not support system call injection.

RETURN VALUES

Upon successful completion, the pr_creat() function's return value is
that described in creat(2). Otherwise, -1 is returned and errno is set
to ENOSYS to indicate that the system call could not be injected.

ERRORS

For the full list of errors see the ERRORS section in creat(2).

The pr_creat() 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.

INTERFACE STABILITY

Uncommitted
