Hello Andrew,
I understand that you do not want to create env before checking if TLS
is configured. But, please, do not call abort() in glp_config().
Otherwise your abort statement will stop the complete application.
Imagine that being the webserver for a site on which a webapp is
deployed which calls the GLPK library.
Either simply return NULL. Or define a value with signifies an error:
glpk.h:
#define GLP_INVALID ((const void *) -1)
env/env.c:
const char *glp_config(const char *option)
{
...
return GLP_INVALID;
...
}
Best regards
Heinrich Schuchardt
