t_sndudata(3n) -- send a data unit
|
|
This function is used in connectionless mode to send a data unit to another transport user. fd identifies the local transport endpoint through which data will be sent, and unitdata points to a t_unitdata structure containing the following members: struct netbuf addr; struct netbuf opt; struct netbuf u... |

t_strerror(3n) -- produce an error message string
|
|
t_strerror maps the error number in errnum that corresponds to an XTI error to a language-dependent error message string and returns a pointer to the string. The string pointed to will not be modified by the program, but may be overwritten by a subsequent call to the t_strerror function. The string is not terminated by a newline character. The language for error message strings written by t_strerro... |

t_sync(3n) -- synchronize transport library
|
|
For the transport endpoint specified by fd, t_sync synchronizes the data structures managed by the transport library with information from the underlying transport provider. In doing so, it can convert a raw file descriptor [obtained via open(2), dup(2), or as a result of a fork(2) and exec(2)] to an initialized transport endpoint, assuming that file descriptor referenced a transport provider. This function also allows two coopera... |
|
t_unbind(3n) -- disable a transport endpoint
|
|
The t_unbind function disables the transport endpoint specified by fd which was previously bound by t_bind(3N). On completion of this call, no further data or events destined for this transport endpoint will be accepted by the transport provider. This function resides within both the X/Open compliant libxnet and the SVR4 compliant libnsl Network Services libraries. Network Services applications which require X/Open ... |

ualarm(3c) -- generate a SIGALRM signal in ``useconds'' microseconds
|
|
The ualarm() function causes the SIGALRM signal to be generated for the calling process after the number of real-time microseconds specified by the useconds argument has elapsed. When the interval argument is nonzero, repeated timeout notification occurs with a period in microseconds specified by the interval argument. If the notification signal, SIGALRM, is not caught or ignored, the calling process is terminated. The ualarm() function returns the number of microseconds remaining from the previ... |

udmalib(3x) -- user-level access to DMA hardware
|
|
On Challenge and Onyx systems, These routines form the basis for a simplified interface to DMA engines, usrdma(7m) devices. These routines are included in a program by compiling with the -ludma option. Currently, the only supported DMA engine is for VME on the Challenge/Onyx series. As DMA engines become available for other hardware platforms, support will be provided through this interface. An application would use the routines dma_open and dma_close to allocate and deallocate access to a DMA e... |

ufmCloseTypeface(3w) -- close a typeface
|
|
ufmCloseTypeface closes an open typeface. Once a typeface is closed, you can no longer use the handle that was assigned to that typeface. typefaceHandle is a typeface handle that was returned by ufmOpenTypeface. That must be the handle of an open typeface. |
|
ufmFree(3w) -- free an area of memory that was allocated by UFM
|
|
ufmFree frees the data the pointer ufmPointer points to. You must use the function ufmFree to free any objects that were allocated by the Universal Font Manager (UFM), unless an alternate UFM function is explicitly specified for the object. For example, your program should call ufmFree if it wants to free the memory allocated for a font path by ufmGetFontPath. If it wants to free character bi... |
|
ufmFreeBitmap(3w) -- free a character bitmap
|
|
ufmFreeBitmap frees the memory ufmGetBitmap allocated for one or more data structures of the type ufmBitmap. When ufmGetBitmap allocates an array of one or more data structures of the type ufmBitmap, it returns the number of allocated data structures (nCharBitmaps) and the address of that array (charBitmaps). When you are finished with that array, you can free it by calling ufm... |
|
ufmFreeCharMetrics(3w) -- free character metrics
|
|
ufmFreeCharMetrics frees the memory ufmGetCharMetrics allocated for one or more data structures of the type ufmCharMetrics. When ufmGetCharMetrics allocates an array of one or more data structures of the type ufmCharMetrics, it returns the number of allocated data structures (nCharMetrics) and the address of that array (charMetrics). When you... |
|
ufmFreeExactOutline(3w) -- free an exact character outline
|
|
ufmFreeExactOutline frees the memory ufmGetExactOutline allocated for one or more data structures of the type ufmExactOutline. When ufmGetExactOutline allocates an array of one or more data structures of the type ufmExactOutline, it returns the number of allocated data structures (nOutlines) and the address of that array (outlines). ... |
|
ufmFreeFontInfo(3w) -- free font information
|
|
ufmFreeFontInfo frees the memory ufmGetFontInfo allocated for a data structure of the type ufmFont. When ufmGetFontInfo allocates a data structure of the type ufmFont, it returns the address of that data structure (font). When you are finished with that data structure, you can free it by calling ufmFreeFontInfo with the addr... |
|
ufmFreeTypefaceInfo(3w) -- free typeface information
|
|
ufmFreeTypefaceInfo frees the memory ufmGetTypefaceInfo allocated for a data structure of the type ufmTypeface. When ufmGetTypefaceInfo allocates a data structure of the type ufmTypeface, it returns the address of that data structure (typeface). When you are finished with that data structure, you can free it by calling ufm |
|
ufmFreeTypefaceList(3w) -- free a list of typefaces
|
|
ufmFreeTypefaceList frees the memory ufmGetTypefaceList allocated for an array of the data structures of the type ufmTypeface. When ufmGetTypefaceList allocates an array of the data structures of the type ufmTypeface, it returns the number of allocated data structures (nTypefaces) and the address of that data structure (typefaces). W... |
