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

pr_creat
inject creat system call into victim process

Process Control Library (libproc, -lproc)
#include <libproc.h>

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

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.

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.

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

The pr_creat() function will fail if:

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.
