dmedia/dmGetError(3d) -- retrieve an error number, message, and detail for Digital Media errors
|
|
pid The process id in which to check for an error. In dmGetError(), this defaults to the current pid as returned by getpid(2). errornum A pointer to an integer into which the error number of the current error will be loaded. If errornum is NULL, it will be ignored. error_detail The address of a char array of size DM_MAX_ERROR_DETAIL, allocated in the application's memory space. A detailed description of the error will be loaded into this array, if such a description is available. This string wi... |

dmedia/dmGetUST(3d) -- get digital media Unadjusted System Time (UST)
|
|
dmGetUST(3dm) returns a high-resolution, unsigned 64-bit number to processes using libdmedia. The value of UST is the number of nanoseconds since the system was booted. Though the resolution is 1 nanosecond, the actual accuracy may be somewhat lower and varies from system to system. Unlike other representations of time under UNIX, the value from which this timestamp derives is never adjusted; therefore it is guaranteed to be monotonically increasing. Typically, the UST is used as a timestamp; th... |

handle DMGSMdecoder structure, created by dmGSMDecoderCreate(3dm), specifies the signal processing parameters. ibuf pointer to input compressed data buffer, an array of a multiple of 33 bytes. The data format is unsigned char (8-bit). obuf pointer to output sample data buffer, an array of size of a multiple of 160. The data format is short (16-bit). The samples are assumed to be two's complement. The sampling rate must be 8 kHz. numSamples number of sample in the output buffer to be generated. ... |
