+*  NAME
+*
+*  str2int - convert character string to value of int type
+*
+*  SYNOPSIS
+*
+*  #include "misc.h"
+*  int str2int(const char *str, int *val);
+*
+*  DESCRIPTION
+*
+*  The routine str2int converts the character string str to a value of
+*  integer type and stores the value into location, which the parameter
+*  val points to (in the case of error content of this location is not
+*  changed).
+*
+*  RETURNS
+*
+*  The routine returns one of the following error codes:
+*
+*  0 - no error;
+*  1 - value out of range;
+*  2 - character string is syntactically incorrect. */
