NAME

       comedi_strerror - return string describing Comedilib error code

SYNOPSIS

       #include <comedilib.h>

       const char * comedi_strerror(int errnum);

DESCRIPTION

       When a Comedilib function fails, it usually returns -1 or NULL, depending on the return
       type. An internal library variable stores an error number, which can be retrieved with
       comedi_errno. This error number can be converted to a human-readable form by the functions
       comedi_perror or comedi_strerror.

       These functions are intended to mimic the behavior of the standard C library functions
       perror, strerror, and errno. In particular, Comedilib functions sometimes return an error
       that is generated inside the C library; the comedi error message in this case is the same
       as the C library.

       The function comedi_strerror returns a pointer to a character string describing the
       Comedilib error errnum. The returned string may be modified by a subsequent call to a
       strerr or perror function (either the libc or Comedilib versions). An unrecognized error
       number will return a pointer to the string “undefined error”, or similar.
