unsigned int buflen,
int is_user,
unsigned long * maskp,
int nmaskbits);
ARGUMENTS¶
bufread nul-terminated user string from this buffer
buflen
buffer size in bytes. If string is smaller than this then
it must be terminated with a \0.
is_user
location of buffer, 0 indicates kernel space
maskp
write resulting mask here
nmaskbits
number of bits in mask to be written
DESCRIPTION¶
Input format is a comma-separated list of decimal numbers and ranges. Consecutively set bits are shown as two hyphen-separated decimal numbers, the smallest and largest bit numbers set in the range. Returns 0 on success, -errno on invalid input strings.ERROR VALUES¶
