Detailed Description

PJLIB Error Subsystem.

Macro Definition Documentation

#define PJ_ERRNO_SPACE_SIZE   50000

PJ_ERRNO_SPACE_SIZE is the maximum number of errors in one of the error/status range below.

#define PJ_ERRNO_START   20000

PJ_ERRNO_START is where PJLIB specific error values start.

#define PJ_ERRNO_START_STATUS   (PJ_ERRNO_START + PJ_ERRNO_SPACE_SIZE)

PJ_ERRNO_START_STATUS is where PJLIB specific status codes start. Effectively the error in this class would be 70000 - 119000.

#define PJ_ERRNO_START_SYS   (PJ_ERRNO_START_STATUS + PJ_ERRNO_SPACE_SIZE)

PJ_ERRNO_START_SYS converts platform specific error codes into pj_status_t values. Effectively the error in this class would be 120000 - 169000.

#define PJ_ERRNO_START_USER   (PJ_ERRNO_START_SYS + PJ_ERRNO_SPACE_SIZE)

PJ_ERRNO_START_USER are reserved for applications that use error codes along with PJLIB codes. Effectively the error in this class would be 170000 - 219000.

#define pj_perror_wrapper_3 (   arg)    pj_perror_3 arg

Parameters
argLog expression.
#define pj_perror_wrapper_4 (   arg)    pj_perror_4 arg

Internal function to write log with verbosity 4. Will evaluate to empty expression if PJ_LOG_MAX_LEVEL is below 4.

Parameters
argLog expression.
#define pj_perror_wrapper_5 (   arg)

Internal function to write log with verbosity 5. Will evaluate to empty expression if PJ_LOG_MAX_LEVEL is below 5.

Parameters
argLog expression.
#define pj_perror_wrapper_6 (   arg)

Internal function to write log with verbosity 6. Will evaluate to empty expression if PJ_LOG_MAX_LEVEL is below 6.

Parameters
argLog expression.
