NAME

syscall_get_return_value - get the return value of a traced system call

SYNOPSIS

long syscall_get_return_value(struct task_struct * task, struct pt_regs * regs);

ARGUMENTS

task

task of interest, must be blocked

regs


task_pt_regs of task

DESCRIPTION

Returns the return value of the successful system call. This value is meaningless if syscall_get_error returned nonzero.

It's only valid to call this when task is stopped for tracing on exit from a system call, due to TIF_SYSCALL_TRACE or TIF_SYSCALL_AUDIT.
