Hi,
In the vi editor, I could do a search and replace:
:%s/work/play/g
but how do I do this for a string/text with space? like if I want to replace all text of "come here" with text "go there"? I've tried with quotes, double quotes, back slash, none of them worked.
thanks!... (1 Reply)

mlockall
mlockall(3C) Standard C Library Functions mlockall(3C)NAME
mlockall, munlockall - lock or unlock address space
SYNOPSIS
#include <sys/mman.h>
int mlockall(int flags);
int munlockall(void);
DESCRIPTION
The mlockall() function locks in memory all pages mapped by an address space.
The value of flags determines whether the pages to be locked are those currently mapped by the address space, those that will be mapped in
the future, or both:
MCL_CURRENT Lock current mappings
MCL_FUTURE Lock future mappings
If MCL_FUTURE is specified for mlockall(), mappings are locked as they are added to the address space (or replace existing mappings), pro-
vided sufficient memory is available. Locking in this manner is not persistent across the exec family of functions (see exec(2)).
Mappings locked using mlockall() with any option may be explicitly unlocked with a munlock() call (see mlock(3C)).
The munlockall() function removes address space locks and locks on mappings in the address space.
All conditions and constraints on the use of locked memory that apply to mlock(3C) also apply to mlockall().
Locks established with mlockall() are not inherited by a child process after a fork(2) call, and are not nested.
RETURN VALUES
Upon successful completion, the mlockall() and munlockall() functions return 0. Otherwise, they return -1 and set errno to indicate the
error.
ERRORS
The mlockall() and munlockall() functions will fail if:
EAGAIN Some or all of the memory in the address space could not be locked due to sufficient resources. This error condition
applies to mlockall() only.
EINVAL The flags argument contains values other than MCL_CURRENT and MCL_FUTURE.
EPERM The {PRIV_PROC_LOCK_MEMORY} privilege is not asserted in the effective set of the calling process.
