9.193 MCLOCK — Time function ¶

Description:

Returns the number of clock ticks since the start of the process, based on the function clock(3) in the C standard library.

This intrinsic is not fully portable, such as to systems with 32-bit INTEGER types but supporting times wider than 32 bits. Therefore, the values returned by this intrinsic might be, or become, negative, or numerically less than previous values, during a single run of the compiled program.

Standard:

GNU extension

Class:

Function

Syntax:

RESULT = MCLOCK()

Return value:

The return value is a scalar of type INTEGER(4), equal to the number of clock ticks since the start of the process, or -1 if the system does not support clock(3).
