mscanf Scilab Group Scilab Function mscanf
NAME
mfscanf - scan data from file mscanf - scan data from input msscanf
- scan data from string
CALLING SEQUENCE
[n,a1,...,am]=mfscanf(fd,format);
data=mfscanf(fd,format);
[n,a1,...,am]=mscanf(format);
data=mscanf(format);
[n,a1,...,am]=msscanf(str,format);
data=msscanf(str,format);
PARAMETERS
fd : scalar, file descriptor given by mopen (it's a positive
integer). The value -1 refers to the default file ( i.e the last opened
file).
format : a character string, a C like format.
str : a character string, string to be scanned.
n : a scalar integer, the number or data really read.
a1,...,am : Output variables. if m>n the n+1:n last ai' are set to [].
data : a list formed by the data really read.
DESCRIPTION
The mscanf(), mfscanf(), and msscanf() functions are interface for
C-coded version of fscanf, sscanf and scanf functions.
The mscanf(), mfscanf(), and msscanf() functions read character data,
interpret it according to a format (see cformat), and store the converted
results into variables. The format parameter contains conversion
specifications used to interpret the input.
These functions read their input from the following sources:
mscanf() : Reads from the Scilab input.
mfscanf() : Reads from the file given by the file descriptor fd.
msscanf() : Reads from the character string specified by the str
parameter.
EXAMPLE
[n,a1,a2]=msscanf('123 456','%i %s')
[n,a1,a2,a3]=msscanf('123 456','%i %s')
data=msscanf('123 456','%i %s')
fd=mopen(SCI+'/scilab.star','r')
mfscanf(fd,'%s %s %s')
mclose(fd)
