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

Pxecbkpt, Pxecwapt, Lxecbkpt, Lxecwaptstep over a breakpoint or watchpoint

Process Control Library (libproc, -lproc)

#include <libproc.h>

Pxecbkpt(struct ps_prochandle *P, ulong_t saved);

Pxecwapt(struct ps_prochandle *P, ulong_t saved);

Lxecbkpt(struct ps_lwphandle *L, ulong_t saved);

Lxecwapt(struct ps_lwphandle *L, ulong_t saved);

The () and () functions step over a breakpoint or watchpoint respectively in the corresponding process handle P. The functions execute the original instruction that was at the current program counter, provided by saved, and then leave the process stopped at the next instruction.

The process must be stopped at the time that the () or () functions are called.

The () and () functions are identical to Pxecbkpt() and Pxecwapt(), respectively; except rather than operating on the process as a whole, they operate on the thread handle L. These functions only require that the thread represented by L be stopped and not the entire process.

Upon successful completion, the Pxecbkpt(), Pxecwapt(), Lxecbkpt(), and Lxecwapt() functions return having executed the original instruction at saved. Otherwise, is returned and is set to indicate the error.

For a full list of errors see the section in proc(5). The Pxecbkpt(), Pxecwapt(), Lxecbkpt(), and Lxecwapt() functions will fail if:

Either P or L is not stopped.

See in libproc(3LIB).
