Function Documentation

void* QFR_fileCtxConstruct (  QFR_fileCtx *  ctx, const QFR_fileCfg *  cfg )

Constructs the file resolution translation context. Returns: Pointer to the next location Parameters: ctx  The context to construct cfg  The configuration

int QFR_fileCtxSizeof (  const QFR_fileCfg *  cfg  )

Returns the size in bytes need to hold the file resolution context. Parameters: cfg  The file resolution configuration

static unsigned int size (  const char *  stem, const char *  facility, const char *  area )  [static]

Gets the size, in bytes of the file stem. Returns: The size, in bytes, of the file stem Parameters: stem  User specified stem facility  If stem is NULL, then an environment variable of the form <facility><area> is constructed and a translation on it is attempted. area  The area (_F_PROD, _F_DEV, _F_TEST)

static const char * translate (  const char *  facility, const char *  area )  [static]

Translates the environment variable whose name looks like <facility>_<area>. Returns: Pointer to the translated environment variable
