NAME

       pmem2_errormsg() - returns last error message

SYNOPSIS

              #include <libpmem2.h>

              const char *pmem2_errormsg(void);

DESCRIPTION

       If  an error is detected during the call to a libpmem2(7) function, the application may retrieve an error
       message describing the reason of  the  failure  from  pmem2_errormsg().   The  error  message  buffer  is
       thread-local;  errors  encountered in one thread do not affect its value in other threads.  The buffer is
       never cleared by any library function; its content is significant only when the return value of the imme‐
       diately preceding call to a libpmem2(7) function indicated an error.  The application must not modify  or
       free  the error message string.  Subsequent calls to other library functions may modify the previous mes‐
       sage.

RETURN VALUE

       The pmem2_errormsg() function returns a pointer to a static buffer  containing  the  last  error  message
       logged for the current thread.  If errno was set, the error message may include a description of the cor‐
       responding error code as returned by strerror(3).
