Ignored Return Value
The return value of ep_strdup_printf() is never checked in the highlighted execution scenario. - If the return value can indicate an error, the error will be ignored if the highlighted code executes.
- The return value of ep_strdup_printf() is checked 97% of the time in this project. CodeSonar is configured to enforce Ignored Return Value checks for any function whose return value is checked at least 96% of the time, unless the function is used fewer than 20 times. (To modify these thresholds, use configuration file parameters RETURN_CHECKER_SAMPLE_SIZE and RETURN_CHECKER_RATIO. To exempt ep_strdup_printf() from the Ignored Return Value check, use configuration file parameter RETURN_CHECKER_IGNORED_FUNCS).
