BUFF_GET_ENV - (MACRO) Sets up call to kjb_get_env
Example compile flags (system dependent):
-DLINUX_X86_64 -DLINUX_X86_64_OPTERON -DGNU_COMPILER
-lKJB -lfftw3 -lgsl -lgslcblas -ljpeg -lSVM -lstdc++ -lpthread -lSLATEC -lg2c -lacml -lacml_mv -lblas -lg2c -lncursesw
const char *env_var,
char env_var_val[ ]
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!
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
