Typedef Documentation

typedef unsigned short mfc_t

Definition at line 25 of file tm.h.

typedef union tm_hdrs tm_hdrs_t

tm_hdrs_t is a combination of all the header types, defining the minimum size struct we need to read in to understand the rest of the message. The message layout is best understood in the tm_msg_t structure, but in actual practice, I will use tm_hdrs_t, then access the data directly.

typedef unsigned short tm_hdrw_t

Definition at line 26 of file tm.h.

typedef struct tm_msg tm_msg_t

tm_msg_t is the logical format of TM messages to and from TMbfr.

typedef unsigned long tmcks_t

Here is the call graph for this function:

const char* tm_dev_name ( const char * base )

Build a standard name for QNX6 resource.

#include "tm.h" const char *tm_dev_name(const char *base);

If the input base string does not start with a '/', tm_dev_name() builds a string of the form: /dev/huarp/exp/base where exp is the current value of the environment variable "Experiment" and base is the input argument string. This is the standard means of building resource names within the ARP Data Acquisition System architecture.

Returns a pointer to a static buffer containing the expanded name. You must save the string if it is needed for long.
