Function Documentation

libpcap_write_file_header()

bool libpcap_write_file_header ( FILE *  pfile, int  linktype, int  snaplen, bool  ts_nsecs, uint64_t *  bytes_written, int *  err  )

extern

Write the file header to a dump file. Returns true on success, false on failure. Sets "*err" to an error code, or 0 for a short write, on failure

libpcap_write_packet()

bool libpcap_write_packet ( FILE *  pfile, time_t  sec, uint32_t  usec, uint32_t  caplen, uint32_t  len, const uint8_t *  pd, uint64_t *  bytes_written, int *  err  )

extern

Write a record for a packet to a dump file. Returns true on success, false on failure.

pcapng_write_section_header_block()

bool pcapng_write_section_header_block ( FILE *  pfile, GPtrArray *  comments, const char *  hw, const char *  os, const char *  appname, uint64_t  section_length, uint64_t *  bytes_written, int *  err  )

extern

Write a section header block (SHB)

Parameters

pfile	Write information
comments	Comments on the section, Optinon 1 opt_comment UTF-8 strings containing comments that areassociated to the current block.
hw	HW, Optinon 2 shb_hardware An UTF-8 string containing the description of the hardware used to create this section.
os	Operating system name, Optinon 3 shb_os An UTF-8 string containing the name of the operating system used to create this section.
appname	Application name, Optinon 4 shb_userappl An UTF-8 string containing the name of the application used to create this section.
section_length	Length of section
bytes_written	Number of written bytes
err	Error type
