USDUMPLOCK(3P)                                                  USDUMPLOCK(3P)


NAME
     usdumplock - dump out information about a specific lock

C SYNOPSIS
     #include <ulocks.h>
     #include <stdio.h>

     int usdumplock (ulock_t lock, FILE *fd, const char *str);

DESCRIPTION
     usdumplock dumps information about lock in a readable form.  This
     information is written to the file descriptor given by fd.  The
     information printed includes where in memory the lock resides, whether it
     is locked or free, and the metering and debugging information (see
     usctllock(3P)).  The argument str is simply printed as a string, and can
     be used to aid in identifying where usdumplock was called from.

SEE ALSO
     usinit(3P), usctllock(3P).

DIAGNOSTICS
     Upon successful completion, a value of 0 is returned. Otherwise, a value
     of -1 is returned and errno is set to indicate the error.
