DESCRIPTION

24       The  scsi_hba_lookup_capstr() function attempts to match capstr against
25       a known set of capability strings. If found, the defined index for  the
26       matched capability is returned.

RETURN VALUES

128       The scsi_hba_lookup_capstr()  function  returns  a  non-negative  index
129       value that corresponds to the capability string. If the string does not
130       match a known capability, -1 is returned.
131

CONTEXT

133       The scsi_hba_lookup_capstr() function can be called from  user,  inter‐
134       rupt, or kernel context.
