SYNOPSIS

int priv_getbyname(const char *priv, int flags);
INTERFACE LEVEL

DESCRIPTION
The priv_getbyname() function maps a privilege name to a privilege num‐
ber for use with the priv_*() kernel interfaces.
If PRIV_ALLOC is passed as a flag parameter, an attempt is made to
allocate a privilege if it is not yet defined. The newly allocated
privilege number is returned.
Privilege names can be specified with an optional priv_ prefix, which
is stripped.
Privilege names are case insensitive but allocated privileges preserve
case.
Allocated privileges can be at most {PRIVNAME_MAX} characters long and
can contain only alphanumeric characters and the underscore character.
RETURN VALUES
This function returns the privilege number, which is greater than or
equal to 0, if it succeeds. It returns a negative error number if an
error occurs.
ERRORS
EINVAL
This might be caused by any of the following
o The flags parameter is invalid.
o The specified privilege does not exist.
o The priv parameter contains invalid charac‐
ters.
ENOMEM
There is no room to allocate another privilege.
ENAMETOOLONG
An attempt was made to allocate a privilege that was
longer than {PRIVNAME_MAX} characters.
CONTEXT
This functions can be called from user and kernel contexts.
