QNX SDP8.0C Library ReferenceAPIDeveloper

Get information about a log file

Synopsis:

#include <slog2_parse.h>

int slog2_get_log_info( slog2_log_t log,
                        slog2_log_info_t *log_info );

Arguments:

log
A log handle previously returned by slog2_open_log().
log_info
A pointer to a slog2_log_info structure where the function can store the information about the log.

Library:

libslog2parse

Description:

The slog2_get_log_info() function gets information about a log file and stores it in the given slog2_log_info structure.

Note:
Before you call this function, you must use the SLOG2_LOG_INFO_INIT macro to initialize the slog2_log_info structure. For example:
slog2_log_info_t log_info = SLOG2_LOG_INFO_INIT;

The slog2_log_info structure is defined as follows:

typedef struct {
    uint32_t            size;
    uint32_t            num_buffers;
    uint32_t            owner_pid;
    const char         *buffer_set_name;
    uint8_t             verbosity_level;
} slog2_log_info_t;

The members include:

size
The size of the structure, which is used to determine the version of the software.
num_buffers
The number of buffers contained in this log.
owner_pid
The process ID of the creator of the log.
buffer_set_name
The descriptive name of this log. Don't modify the string that this member points to.
verbosity_level
The global verbosity level of the log; one of the following (defined in <sys/slog2.h>):
  • SLOG2_SHUTDOWN
  • SLOG2_CRITICAL
  • SLOG2_ERROR
  • SLOG2_WARNING
  • SLOG2_NOTICE
  • SLOG2_INFO
  • SLOG2_DEBUG1
  • SLOG2_DEBUG2
