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

NAME

       ps_pread, ps_pwrite, ps_pdread, ps_pdwrite, ps_ptread, ps_ptwrite - interfaces in libthread_db that target process memory access

SYNOPSIS

       #include <proc_service.h>

	ps_err_e ps_pread(struct ps_prochandle *ph, psaddr_t addr, void *buf, size_t size);

       ps_err_e ps_pwrite(struct ps_prochandle *ph, psaddr_t addr, const void *buf, size_t size);

       ps_err_e ps_pdread(struct ps_prochandle *ph, psaddr_t addr, void *buf, size_t size);

       ps_err_e ps_pdwrite(struct ps_prochandle *ph, psaddr_t addr, const void *buf, size_t size);

       ps_err_e ps_ptread(struct ps_prochandle *ph, psaddr_t addr, void *buf, size_t size);

       ps_err_e ps_ptwrite(struct ps_prochandle *ph, psaddr_t addr, const void *buf, size_t size);

DESCRIPTION

       These  routines copy data between the target process's address space and the controlling process. ps_pread() copies size bytes from address
       addr in the target process into buf in the controlling process. pr_pwrite() is like ps_pread() except that the direction  of  the  copy	is
       reversed; data is copied from the controlling process to the target process.

       ps_pdread()  and ps_ptread() behave identically to ps_pread(). ps_pdwrite() and ps_ptwrite() behave identically to ps_pwrite(). These func-
       tions can be implemented as simple aliases for the corresponding primary functions. They are artifacts of history that must be maintained.

RETURN VALUES

       PS_OK	       The call returned successfully. size bytes were copied.

       PS_BADADDR      Some part of the address range from addr through addr+size-1 is not part of the target process's address space.

       PS_ERR	       The function did not return successfully.
