gets a line of text from a file
This routine runs fgets() to fetch a line of text from a file (advancing file pointer) and removes trailing newline. fgets() does not recognize '\r
' as an EOL and will read past it.
buf,: | string buffer to receive read data | |
n,: | maximum number of bytes to read | |
fd,: | file descriptor structure |

int G_getl2 | ( | char * | buf, | |
int | n, | |||
FILE * | fd | |||
) |
gets a line of text from a file of any pedigree
This routine is like G_getl() but is more portable. It supports text files created on various platforms (UNIX, MacOS9, DOS), i.e. \n (\012)
, \r (\015)
, and \r\n (\015\012)
style newlines.
Reads in at most n characters from stream and stores them into the buffer pointed to by buf. Reading stops after an EOF or a newline. New line is not stored in the buffer. At least n+1 must be allocated for the string buffer.
buf,: | string buffer to receive read data, at least n+1 must be allocated | |
