# regulator\_is\_enabled(9)

is the regulator output enabled

## NAME

regulator\_is\_enabled - is the regulator output enabled

## SYNOPSIS

**int regulator\_is\_enabled(struct regulator \*** *regulator***);**

## ARGUMENTS

*regulator*

regulator source

## DESCRIPTION

Returns positive if the regulator driver backing the source/client has requested that the device be enabled, zero if it hasn't, else a negative errno code.

Note that the device backing this regulator handle can have multiple users, so it might be enabled even if **regulator\_enable** was never called for this particular source.
