g2c_set_log_level()

int g2c_set_log_level

(

int

new_level

)

Use this to set the global log level.

Set it to -1 to turn off all logging. Set it to 0 to show only errors, and to higher numbers to show more and more logging details. If logging is not enabled when building NCEPLIBS-g2c, this function will do nothing.

Parameters

new_level

The new logging level.

Returns

G2_NO_ERROR No error.
