.SH "NAME"
__bitmap_parselist \- convert list format ASCII string to bitmap
.SH "SYNOPSIS"
.HP \w'int\ __bitmap_parselist('u
.BI "int __bitmap_parselist(const\ char\ *\ " "buf" ", unsigned\ int\ " "buflen" ", int\ " "is_user" ", unsigned\ long\ *\ " "maskp" ", int\ " "nmaskbits" ");"
.SH "ARGUMENTS"
.PP
\fIbuf\fR
.RS 4
read nul\-terminated user string from this buffer
.RE
.PP
\fIbuflen\fR
.RS 4
buffer size in bytes\&. If string is smaller than this then it must be terminated with a \e0\&.
.RE
.PP
\fIis_user\fR
.RS 4
location of buffer, 0 indicates kernel space
.RE
.PP
\fImaskp\fR
.RS 4
write resulting mask here
.RE
.PP
\fInmaskbits\fR
.RS 4
number of bits in mask to be written
.RE
.SH "DESCRIPTION"
.PP
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\&.
.PP
Returns 0 on success, \-errno on invalid input strings\&. Error values:
\fB\-EINVAL\fR: second number in range smaller than first
\fB\-EINVAL\fR: invalid character in string
\fB\-ERANGE\fR: bit number specified too large for mask
