BUFF_GET_ENV - (MACRO) Sets up call to kjb_get_env

SYNOPSIS

#include "l/l_sys_lib.h"

Example compile flags (system dependent):
  -DLINUX_X86_64 -DLINUX_X86_64_OPTERON  -DGNU_COMPILER 
   -I/home/kobus/include
   -L/home/kobus/misc/load/linux_x86_64_opteron -L/usr/lib/x86_64-linux-gnu
  -lKJB                               -lfftw3  -lgsl -lgslcblas -ljpeg  -lSVM -lstdc++                    -lpthread -lSLATEC -lg2c    -lacml -lacml_mv -lblas -lg2c      -lncursesw 


int BUFF_GET_ENV
(
	const char *env_var,
	char env_var_val[ ]
);

DESCRIPTION

The max_len parameter is set to sizeof(env_var_val). Using sizeof to set the buffer size is recomended where applicable, as the code will not be broken if the buffer size changes. HOWEVER, neither this method, nor the macro, is applicable if line is NOT a character array. If line is declared by "char *line", then the size of line is the number of bytes in a character pointer (usually 4), which is NOT what is normally intended. You have been WARNED!
