Take two C files as an example:The adc_device.c, Adc_ driver.c, which should have been compiled separately into adc_Device.ko and adc_Driver.ko, are compiled into a KO file!Method of Adoption:First step, modify C file1, remove adc_device.c file

Blum's book only speaks of the C language Call assembly, which does not speak of assembly call C. I tried it myself.The final test was successful, and it was written here to share with you. During the countless errors, countless anomalies, I am not

First of all, I am also learn from other people's source code. Because if still follow from the beginning to look at VC + + to do the words must be too late, then I directly to the analysis to understand other people's code, learn from it and

The most common use of variable-length parameters in the C language is the following two functions:int printf (const char *format, ...); int scanf (const char *format, ...);So how do they implement support into parameters? The implementation part of
