Use the following format:

ioctl (fd_atm,ATMIOC_GETATMADDR, &address);

address is an atm_address_t structure.

The argument is a pointer to an empty atm_address_t structure (described in Table 4-2).

If successful, ATMIOC_GETATMADDR returns zero. The out values should be read.

On failure, the ioctl() returns -1 with an error stored in errno. For descriptions of individual errors, see “Errors”.

The retrieved ATM address, described in Table 4-2 and Figure 4-1, is copied into the call's argument. The address can be either the ATM network service access point (NSAP) or the native-E.164 format.

Figure 4-1. ATM Address: NSAP Format

The atm_address_t structure is defined in the sys/atm_user.h file, as follows:

typedef struct atm_address {
      char addrType;
      union {
          nsap_address_t nsap;
          e164_address_t e164;
      } addr;
} atm_address_t;
typedef char nsap_address_t[20];
typedef struct e164_address {
      unsigned char len;
      char addr[15];
} e164_address_t;

Possible errors include:

Use the following format:

ioctl (fd_atm, ATMIOC_GETATMLAYERINFO, &layerinfo);

layerinfo is an atm_layerinfo_t structure.

The argument is a pointer to an empty atm_layerinfo_t structure.

If successful, ATMIOC_GETATMLAYERINFO returns zero. The out values should be read.

On failure, the ioctl() returns -1 with an error stored in errno. For descriptions of individual errors, see “Errors”.

The retrieved values are copied to the structure pointed to by the call's argument, described in Table 4-3.

The atm_layerinfo_t structure is described in Table 4-3, and defined in the sys/atm_user.h file, as follows:

typedef struct {
      int maxVPCs;
      int maxVCCs;
      int configuredVPCs;
      int configuredVCCs;
      int maxVPIbits;
      int maxVCIbits;
      int uniType;
} atm_layerinfo_t;

Possible errors include:

Use the following format:

ioctl (fd_atm, ATMIOC_GETMIBSTATS, &mibstats);

mibstats is an atm_getmibstats_t structure.

The argument is defined as a pointer to an empty atm_getmibstats_t structure.

If successful, ATMIOC_GETMIBSTATS returns zero. The out values should be read.

On failure, the ioctl() returns -1 with an error stored in errno. For descriptions of individual errors, see “Errors”.

The retrieved values are copied to the structure pointed to by the call's argument, described in Table 4-4.

The atm_getmibstats_t structure is described in Table 4-4, and included below as defined in the sys/atm_user.h file:

typedef struct {
      int receivedCells;
      int droppedReceivedCells;
      int cellsTransmitted;
} atm_getmibstats_t;

Possible errors include:

Use the following format:

ioctl (fd_atm, ATMIOC_GETPORTINFO, &portinfo);

portinfo is an atm_portinfo_t structure.

The argument is a pointer to an empty atm_portinfo_t structure.

If successful, ATMIOC_GETPORTINFO returns zero. The out values should be read.

On failure, the ioctl() returns -1 with an error stored in errno. For descriptions of individual errors, see “Errors”.

The retrieved values are copied to the structure pointed to by the call's argument, described in Table 4-5.

The atm_portinfo_t structure is described in Table 4-5, and defined in the sys/atm_user.h file, as follows:

typedef struct {
      int portOperStatus;
      int portXmitType;
      int portMediaType;
} atm_portinfo_t;

Possible errors include:

Use the following format:

ioctl (fd_atm, ATMIOC_GETVCCTABLEINFO, &sioc);

sioc is an atmsioc_t structure.

The pointer to sioc identifies an instance of an atmsioc_t structure. The atmsioc_t structure should be set up as summarized in Table 4-6. 

If successful, ATMIOC_GETVCCTABLEINFO returns zero. The out values should be read.

On failure, the ioctl() returns -1 with an error stored in errno. For descriptions of individual errors, see “Errors”.

The len field in the argument ( sioc) is updated to contain the actual length of the retrieved data, as described in Table 4-6. The retrieved data is written at the location indicated by the sioc pointer as an array of atm_vcce_t structures. Each table entry is one atm_vcce_t structure, as described in Table 4-7.

The atm_vcce_t structure is described in Table 4-7, and included below as defined in the sys/atm_user.h file. The cellrate_t structure is described in Table 4-8, and is also defined in the sys/atm_user.h file, as follows:

typedef struct {
      int vpi;
      int vci;
      cellrate_t xmit_cellrate;
      cellrate_t recv_cellrate;
      int xmitQOS;

address is an atm_address_t structure.

The atm_address_t structure should be prepared as described in Table 4-9.
